2026 Nobel Prize—Where Breakthroughs Meet Open Sciences


Each October, the Nobel Prizes turn the world’s attention toward the discoveries that have redrawn the boundaries of science. They are science’s most prestigious recognition, and increasingly its most interdisciplinary. Recent laureates have been honored for work spanning quantum dots, machine learning, and molecular medicine, fields that rarely stay within a single discipline’s borders for long.

Open access has a growing role in that story. To date, more than 40 Nobel laureates have published their research in MDPI journals—a body of work spanning genetics, physics, chemistry, and medicine. Publishing openly means a laureate’s findings reach not only fellow scientists, but the students, clinicians, policymakers, and curious readers who would otherwise meet that work only secondhand, if at all. Open access doesn’t just carry Nobel-level research, it amplifies the voice behind it, letting the discovery speak directly to everyone it stands to affect.

This is also where MDPI’s breadth becomes an advantage. With over 500 journals covering the full spectrum of scientific inquiry, our platform mirrors the reality of modern discovery—where breakthroughs increasingly emerge at the intersection of fields, not within the walls of one. It’s this structure that lets us support interdisciplinary work from first submission to global publication, connecting researchers across borders and disciplines alike.

As this year’s laureates are announced, we’ll continue spotlighting where Nobel Prize–winning research intersects with the work of our authors, editors, and reviewers—celebrating both the achievements being recognized and the open access model that helps ensure they reach the widest possible audience.

Explore selected works by Nobel laureates within the MDPI portfolio below, and join us in celebrating the global impact of their ideas.

MDPI INSIGHTS: The CEO’s Letter #39 - Peer Review Week, Chief Publishing Officer, Tu Youyou Award, OASPA & AI

Welcome to the MDPI Insights: The CEO's Letter.

In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.


Opening Thoughts

Recognizing the People Behind Peer Review

September marked Peer Review Week 2026, this year focused on “Peer Review Capacity: Volume, Speed, and Quality.” The theme reflects a challenge across scholarly publishing: research output and submissions continue to grow, while the time and expertise researchers can dedicate to reviewing are finite.

At MDPI, more than 200,000 reviewers contribute their expertise each year. Their work is fundamental to maintaining the quality and integrity of the research we publish, and Peer Review Week gave us an opportunity not only to thank them, but also to reflect on how we can better support their contribution.

This year, we highlighted three commitments that guide our approach: protecting reviewers’ time and judgment, ensuring high-quality and efficient processes, and recognizing and rewarding reviewers for their contribution. We also shared results from our 2026 Voice of the Community surveys. Among 1,627 reviewer respondents, 86% rated their experience with MDPI as “Good” or “Excellent,” 88% said manuscripts matched their expertise, and 92% found our reviewer instructions clear and helpful. From the author perspective, 95% of 16,795 respondents agreed that reviewers’ comments helped improve their manuscripts.

Recognition is an important part of this relationship too. Through our Top 1000 Reviewers program, 743 scholars accepted awards this year, with a combined CHF 526,500 returned directly to the reviewer community through cash awards and APC vouchers. During Peer Review Week, we also created opportunities for reviewers to share their own experiences through webinars, including The Reviewer’s Perspective: Navigating Volume, Speed, and Quality in Peer Review and our UK Reviewer Club.

Peer review ultimately depends on people choosing to give their time and expertise to the work of other researchers. As publishing continues to evolve, including through new technologies and increasing research volumes, we should not lose sight of that human contribution. Thank you to all the reviewers who work with MDPI, and to our colleagues who support them every day.

Inside MDPI

Welcoming Dr. Constanze Schelhorn as MDPI’s Chief Publishing Officer

This month, we announced the appointment of Dr. Constanze Schelhorn as MDPI’s Chief Publishing Officer (CPO). The appointment marks an important step for MDPI and the latest chapter in a journey within the organization that now spans a decade.


Stefan Tochev (CEO, MDPI) with Constanze at STM, Frankfurt, Germany, October 2025.

Constanze joined MDPI in June 2016 and has taken on several different responsibilities across editorial, indexing, and publishing over the years.

Since 2023, she has held leadership roles as Head of Indexing and later Head of Publishing, before taking on the role of Chief Publishing Officer.

I’ve had the opportunity to work with Constanze over many of those years and to see her take on increasingly important responsibilities.

What I’ve always appreciated is the growth mindset and expertise she brings to her work, together with a commitment to quality.

She understands how MDPI works and how the publishing environment is evolving to meet the expectations of the academic communities we serve.

Looking Ahead

Publishing has changed considerably over the past decade, and that change is only accelerating. Research integrity, artificial intelligence, editorial standards, indexing requirements, new publishing models, and changing expectations from researchers and institutions are just some of the areas we are navigating.


Stefan Tochev (CEO, MDPI) with Constanze and Prof. Dr. Manoj Gupta, Editor-in-Chief of MDPI journal Technologies, in Singapore, January 2025.

MDPI has changed considerably too. As we celebrate our 30th anniversary this year, our journal portfolio now includes more than 540 titles, and the scale of our work brings greater opportunities and responsibilities.

Continuing to develop our publishing practices and ensuring that we respond to changes in academic publishing will remain important priorities for us.

Constanze’s experience across several areas of MDPI puts her in a position to help us do that.

As CPO, she will help provide strategic direction across our publishing functions while working with colleagues throughout the organization. She will also represent MDPI with external stakeholders, including industry organizations and indexing partners, ensuring that we remain engaged in the conversations shaping the future of publishing.

“Please join me in congratulating Constanze on her appointment”

Growing Together

There is another aspect of this appointment that I think is worth recognizing about MDPI. I appreciate seeing people develop alongside the organization. Constanze’s journey from joining MDPI in 2016 to becoming our Chief Publishing Officer ten years later is a good example of what can happen when experience, knowledge, and responsibility build over time.

Our 30th anniversary naturally gives us an opportunity to look back at how far MDPI has come. But it should also make us think about the people who will shape where we go next. I’m pleased that Constanze will be one of those people.

Please join me in congratulating Constanze on her appointment as we look forward to continuing to work with her in this new role and seeing what we can accomplish together.

P.S. A fun fact about Constanze: she loves climbing. So, if she’s visiting your city and you’re wondering how to make her feel at home, point her towards the nearest climbing gym.

Here’s a photo from a climbing session during our visit to the Singapore office in January 2025. 

Impactful Research

A Decade of the Tu Youyou Award: Celebrating Scientific Excellence

Few examples demonstrate the potential impact of scientific research as clearly as Professor Tu Youyou's discovery of artemisinin. Her team’s work contributed to the development of artemisinin-based combination therapies for malaria, which the World Health Organization (WHO) recommends as the main treatment for P. falciparum malaria.

Behind that achievement is also a remarkable scientific journey: drawing on knowledge from traditional Chinese medicine, Professor Tu and her team investigated hundreds of extracts before identifying artemisinin and helping transform the treatment of malaria.

This legacy is at the heart of the Tu Youyou Award, established by MDPI in 2016 to recognize outstanding achievements in natural products chemistry and medicinal chemistry.

“Professor Tu Youyou's scientific journey is an extraordinary example”

Ten Years of the Tu Youyou Award

This year marks a decade since the award was established. Over that time, six scholars have been recognized as Tu Youyou laureates for their contributions to research and innovation.

The connection between MDPI and Professor Tu Youyou’s work goes back even further. In 2009, MDPI Founder and President, Dr. Shu-Kun Lin, launched a Special Issue in MDPI journal Molecules commemorating Professor Tu’s 80th birthday, several years before the establishment of the award.

Below is a photo of Professor Tu Youyou with MDPI Founder and President Dr. Shu-Kun Lin during an MDPI visit to congratulate Professor Tu on receiving the 2015 Nobel Prize in Physiology or Medicine.

The 2026 Tu Youyou Award continues this tradition, awarding CHF 100,000, together with a medal and certificate, to recognize the achievements in natural products chemistry and medicinal chemistry.

Scientific Excellence and Impact

Professor Dr. William Gerwick, Chair of the 2026 Tu Youyou Award Committee, recently reflected on what distinguishes the award: “This award is truly special in that it recognizes scientific excellence as well as impact.”

I think this combination is important. Research advances our understanding, but its influence can extend much further: inspiring new discoveries, informing new treatments, addressing societal challenges, and ultimately improving people’s lives.

Professor Tu Youyou's scientific journey is an extraordinary example. Her work combined rigorous scientific investigation with a problem of enormous human importance, ultimately contributing to treatments that have transformed the fight against malaria.

Recognizing researchers who continue this tradition allows us to celebrate both scientific achievement and the broader contribution research can make to society.

Nominations Open Until 31 October

Nominations for the 2026 Tu Youyou Award are now open to scientists with outstanding achievements and contributions in natural products chemistry and medicinal chemistry. Nominations may be submitted by directors of nominees’ host research institutions or scientists within the field. Self-nominations are not accepted.

The nomination deadline is 31 October 2026, with the announcement of the winner planned for March 2027.

Coming Together for Science 

OASPA 2026: Conversations Shaping the Future of Open Access

From 21–23 September, I attended the 2026 Conference of the Open Access Scholarly Publishing Association (OASPA) in Zagreb, Croatia.

 MDPI has been a Platinum Sponsor of the OASPA conference for several years, supporting an event that brings together the open access (OA) community to discuss some of the opportunities and challenges shaping publishing. This year, MDPI also sponsored the conference reception at the City Museum of Zagreb.

The program covered topics from sustainable publishing and research assessment to open infrastructure, new models for OA agreements, and, of course, the growing influence of artificial intelligence (AI). For me, though, the value of conferences like OASPA goes beyond the program. It’s about hearing different perspectives from across publishing, reconnecting with familiar faces, building new relationships, and having conversations that sometimes lead somewhere unexpected.


Stefan Tochev (CEO, MDPI) at the OASPA conference in Zagreb, Croatia.

Open Access in the Age of AI

One discussion I particularly enjoyed was the opening-day panel, “Does open access still matter in a Gen AI world?” As AI continues to become an interface through which people discover and interact with research, making knowledge openly available remains important. But questions around trust, provenance, governance, and responsibility are becoming more difficult to separate from the OA conversation.

Who is responsible for ensuring that AI-generated or AI-mediated information can be trusted? What responsibilities sit with publishers, researchers, institutions, infrastructure providers, and AI companies? And, perhaps most importantly, how do we work together rather than trying to address these challenges in isolation?

There are no simple answers, but hearing these discussions highlighted the fact that many of us across publishing are working with similar questions. Creating spaces where we can explore them together is valuable.

“Who is responsible for ensuring that AI-generated or AI-mediated information can be trusted?”

Conversations That Lead Somewhere

The conference also reminded me of the value of simply meeting people. I had a great conversation with César Pallares from Consortia Colombia about the publishing ecosystem in Colombia and the possibility of exploring a consortium agreement with MDPI in Colombia. César was very open to continuing the conversation, and I’ve already connected this opportunity with colleagues from our Institutional Open Access Program (IOAP) team.

I also caught up with Yvonne Campfens, Executive Director of OA Switchboard, who has recently taken on the role of Director for the Academic Publishing in Europe (APE) conference. We look forward to continuing to support APE as part of MDPI’s broader commitment to academic and publishing-industry events.

And, of course, it was good to connect with familiar faces from previous OASPA conferences and meet new ones. These conversations happen over coffee, between sessions, at receptions, or sometimes while walking through a city. Not every conversation needs to result in a project or partnership. Sometimes the value is simply understanding another perspective, sharing what we’re working on, or beginning a relationship that develops over time.

Thank you to the OASPA team, speakers, moderators, participants, and fellow sponsors for creating that space in Zagreb. I’m pleased that MDPI could once again support the conference and, more importantly, be part of the conversations taking place there. I look forward to seeing where some of them lead.

Closing Thoughts

AI Is Making Science More Accessible. How Do We Keep It Trustworthy?

Artificial Intelligence (AI) is changing how people find, understand, and interact with scientific research.

For decades, one of the biggest barriers to engaging with scientific research was access. Open Access (OA) has helped change that, with around 61% of global journal articles, reviews, and conference papers published in 2025 now openly accessible. AI is now beginning to lower another barrier: understanding. Researchers can quickly navigate large volumes of literature, patients can ask for complex medical research to be explained in plain language, and policymakers can more easily explore findings outside their own areas of expertise.

But easier access and understanding don’t automatically make scientific information easier to trust.

This is the topic explored by our Scientific Communications Lead, Dr. Giulia Stefenelli, in her recent article for Research Information, Scientific literacy must keep pace with artificial intelligence.

A recent study cited in the article found that when GPT-4o was tested without external retrieval and asked to cite recent scientific literature, it fabricated citations in 78–90% of cases. By contrast, OpenScholar, a specialized AI system that retrieves information from millions of OA papers, achieved citation accuracy comparable to human experts.

One line about the gap between AI content generation and verification particularly stood out to me: “Generation is becoming cheap, but verification is not.” While AI can reproduce the appearance of credible scientific information, verifying the underlying data, references, methods, and conclusions still requires time, expertise, and access to the evidence.

“The important question is whether the underlying research can be trusted”

Detection Is Not Verification

Giulia’s distinction between AI detection and research verification is particularly relevant to scholarly publishing. A manuscript can contain AI-assisted language and report sound research. Equally, something written entirely by a person can contain fabricated data, inappropriate methods, or unsupported conclusions. The important question isn’t only “Was AI used?” but whether the underlying research can be trusted.

For publishers, this makes strong editorial processes, expert peer review, research integrity checks, transparency, and human accountability increasingly important.

A Shared Responsibility

Giulia argues that publishers cannot address this challenge alone. Researchers, institutions, publishers, technology providers, and readers all have a role to play in how scientific information is created, evaluated, communicated, and understood.

As AI continues to develop, our understanding of scientific literacy must develop alongside it. Making knowledge accessible and helping people understand it are important. The next question is: how do we make it easier for people to examine where information comes from and decide how much confidence it deserves?

You can read the full article on Research Information. It is a great example of the expertise within MDPI contributing to conversations about the future of scientific publishing and communications. Technology can help us address some of these challenges, but ultimately people must remain accountable for the decisions that shape the scientific record.

Water | Issue Cover Articles Published in the First Half of 2026

The following articles were selected as cover articles of Water (ISSN 2073-4441) in the first half of 2026. These papers cover multiple areas within the journal’s scope, and we hope they will provide useful insights and references for researchers in related fields.

1. “Compound River Floods and Sea Storms: Forcings and Impacts”
by Caterina Canale, Giuseppe Barbaro, Olga Petrucci, Francesca Minniti and Giandomenico Foti
Water 2026, 18(1), 14; https://doi.org/10.3390/w18010014
Available online: https://www.mdpi.com/2073-4441/18/1/14

Cover story: Coastal areas are strategically significant from ecological, anthropic, and economic perspectives, but they are also susceptible to forces that cause inundations. Multiple forcings occurring in close succession in both space and time amplify the effects of a single force, forming a compound event. One example is an atmospheric disturbance that extends from the sea to the mainland, causing a sea storm and a river flood due to heavy rainfall, such as that which occurred in 2015 in Calabria, Southern Italy. This paper focuses on compound river floods and sea storms generated by atmospheric disturbances regardless of their exceptional or nontypical typology. The analysis includes their forcings, correlation, and effects, and is carried out in Calabria, which is an interesting case study due to its peculiarities, which favor the formation of compound events and increase their risk.

2. “Enhancing Osmotic Power Generation and Water Conservation with High-Performance Thin-Film Nanocomposite Membranes for the Mining Industry”
by Sara Pakdaman and Catherine N. Mulligan
Water 2026, 18(2), 248; https://doi.org/10.3390/w18020248
Available online: https://www.mdpi.com/2073-4441/18/2/248

Cover story: This cover highlights the development of a high-performance thin-film nanocomposite (TFN) membrane for pressure-retarded osmosis (PRO) using treated real gold mining wastewater. By incorporating functionalized carbon nanotubes (fCNTs) into the support layer and applying polydopamine (PDA) surface coating, the membrane exhibits enhanced hydrophilicity, water flux, and power density, enabling stable PRO operation following ultrafiltration (UF) and nanofiltration (NF) pretreatment. The results underline the potential of advanced membrane design to support sustainable water management and clean energy recovery in mining operations.

3. “Climate Change and Thermal Dynamics of the Lake Sevan Basin (Armenia): Observational Insights and Future Projections”
by Gor Khachatryan, Artur Gevorgyan, Ashok Vaseashta, Amalya Misakyan, Karsten Rinke, Artak Gevorgyan, Lilit Ghukasyan and Gor Gevorgyan
Water 2026, 18(3), 352; https://doi.org/10.3390/w18030352
Available online: https://www.mdpi.com/2073-4441/18/3/352

Cover story: The Sevan basin is a large intermontane region bordered by the Geghama, Vardenis, Pambak, Areguni, Sevan, and Zangezur mountain ranges. Over half of the basin lies within the 2000–2600 m altitude zone. Its high altitude strongly influences the climatic conditions of Lake Sevan. Analyzing air temperature variability is crucial for predicting seasonal changes in water temperature, ice cover, and lake stratification. The continental climate and mountainous topography further amplify Armenia's vulnerability to climate change. The unique topography of Lake Sevan, along with its large surface area and high altitude, creates microclimatic zones where temperatures can vary substantially, which is essential for developing effective climate adaptation strategies and for gaining valuable insights into how climate change is reshaping seasonal cycles.

4. “Dynamic Structuring of Water at Mesoscopic Length Scales in the Presence of Moderate High-Voltage Fields”
by Elmar C. Fuchs and Jakob Woisetschläger
Water 2026, 18(4), 493; https://doi.org/10.3390/w18040493
Available online: https://www.mdpi.com/2073-4441/18/4/493

Cover story: The observation of Raman sidebands of the vibrational states in water in electrohydrodynamic water bridges can be satisfactorily explained by the presence of dynamically ordered mesoscopic water domains forming under moderate high-voltage fields. These physicochemical signatures demonstrate that electrically stressed water can exhibit collective behaviour distinct from bulk water, with potential relevance for interfacial processes and water-treatment technologies.

5. “Evaluation of Pressure Retarded Osmosis for Energy Generation from Mine Water”
by Giti Nouri, Catherine N. Mulligan, Fuzhan Nasiri, Carmen M. Neculita and Thomas Genty
Water 2026, 18(5), 558; https://doi.org/10.3390/w18050558
Available online: https://www.mdpi.com/2073-4441/18/5/558

Cover story: This study examines the application of mining effluents as feed solutions in pressure-retarded osmosis for energy generation and the prospect of water recycling or safe discharge to the environment. The physiochemical properties of the effluents indicated significant potential for fouling and scaling, which necessitated appropriate pretreatments. It was shown that pretreatments were highly effective in refining the quality of effluents, with a significant removal efficiency of above 90% for ions and heavy metals using nanofiltration. This led to fouling mitigation, higher and more stable power densities of 13 W/m2 and 18.6 W/m2, and potential water reuse or safe environmental discharge. The outcomes of this study are applicable in the mining sector with the potential for water and energy recoveries to contribute to more sustainable mining operations.

6. “Divergent Terrain Responses to Arctic Warming: A Multi-Decadal Analysis in Kaffiøyra, Svalbard (1985–2023)”
by Hong-Son Vo, Chuen-Fa Ni, Yu-Huan Chang, Slawomir Jack Giletycz, Ping-Yu Chang, Nguyen Hoang Hiep and Thai-Vinh-Truong Nguyen
Water 2026, 18(6), 661; https://doi.org/10.3390/w18060661
Available online: https://www.mdpi.com/2073-4441/18/6/661

Cover story: This study quantifies the spatial–temporal variability of glaciers, shorelines, and outwash plains in Kaffiøyra, Svalbard, over four decades using cross-evaluated Landsat and Sentinel-2 imagery. Results reveal systematic retreat across all eight glaciers, with tidewater glaciers experiencing substantially greater terminus area loss compared to land-terminating glaciers. Shoreline erosion was most pronounced on shores exposed to southwesterly summer waves, while significant accretion occurred near the tidewater glacier terminus. Outwash changes remained insignificant despite substantial glacier retreat, indicating that these systems respond to different controls. A moderate negative correlation between glacier terminus area and summer temperatures enabled a simple diagnostic projection model, where locally extrapolated data proved more accurate than downscaled climate scenarios.

by Angelica Lizbeth Álvarez-Mejia, Humberto Salinas-Tapia, Carlos Díaz-Delgado, Juan Manuel Becerril-Lara, Jesús Ramiro Félix-Félix, Boris Miguel López-Rebollar and Juan Antonio García-Aragón
Water 2026, 18(7), 807; https://doi.org/10.3390/w18070807
Available online: https://www.mdpi.com/2073-4441/18/7/807

Cover story: Surface dimple patterns emerge as a powerful strategy for controlling turbulent flow–structure interaction. This study demonstrates how hexagonal dimples on circular piles reshape vortex dynamics in free-surface flow, enhancing energy dissipation and weakening dominant coherent structures. The numerical modeling, validated against PIV measurements, proves essential for accurately capturing the complex flow features and reinforcing the reliability of the results. High-resolution LES reveals a significant reduction in vertical (downward) velocity, as well as a marked attenuation of both horseshoe and wake vortices. These findings establish a new paradigm for passive scour mitigation and improved hydraulic stability.

8. “Large-Scale 2D Rain-on-Grid Hydrodynamic Mapping of Flash and Pluvial Floods with Network-Consistent Return Periods”
by Francesco Macchione, Andrea Antonella Graziano and Dante Nisticò
Water 2026, 18(8), 950; https://doi.org/10.3390/w18080950
Available online: https://www.mdpi.com/2073-4441/18/8/950

Cover story: This study presents the authors’ experience in the application of a fully hydrodynamic model over an entire territory, with direct rainfall input (rain-on-grid approach). This way of conducting flood risk analyses provides hydraulic engineering with an advancement in diagnostics similar to the progress that occurred in medicine with the transition from radiography to contrast-enhanced computed tomography. With radiography, the investigation is focused on a specific point where a symptom is already present. Conversely, a full-body contrast-enhanced scan is a much more powerful tool, detecting all parts of the body, including those where risk hotspots remain asymptomatic. In the rain-on-grid approach, the contrast medium is stormwater. The numerical simulation of all possible stormwater paths generates a comprehensive image of the entire territory.

by Pedro Henrique Garcia de Souza Façanha, Marcelo de Miranda Reis and Igor da Silva Rocha Paz
Water 2026, 18(10), 1207; https://doi.org/10.3390/w18101207
Available online: https://www.mdpi.com/2073-4441/18/10/1207

Cover story: This study presents regionalized rainfall disaggregation coefficients for the Rio de Janeiro Metropolitan Region, Brazil, using high-resolution rainfall data from 109 validated CEMADEN automatic rain gauges. The methodology combines extreme-event extraction, partial-duration series analysis, and a calibrated Pfafstetter-based formulation to estimate representative sub-daily rainfall relationships. The results highlight important differences in the 1 h to 3 h duration range relative to the 24 h rainfall, contributing to improved hydrological design, urban drainage studies, and peak-flow estimation in densely urbanized areas.

11. “Stretching Water Availability: Hydrosolidarity in Drought-Prone Regions”
by Fajr Fradi, Letícia de Freitas Vieira, Rafaela da Silva Alves, Samiramisthaís Souza Linhares, Alexandre Cunha Costa and Eduardo Sávio Passos Rodrigues Martins
Water 2026, 18(11), 1332; https://doi.org/10.3390/w18111332
Available online: https://www.mdpi.com/2073-4441/18/11/1332

Cover story: The Forquilha Valley, located in the semiarid Northeast of Brazil, faces recurrent droughts and chronic challenges in securing water for rural households. Over the past two decades, rainwater-harvesting cisterns have become a central strategy for improving water access. Yet these cisterns do not operate as isolated household infrastructures. Drawing on monitored water-level data, household surveys, and rainfall records, this study reveals that neighbors frequently share stored water, creating networks of hydrosolidarity that extend water availability during dry periods. While rainfall capture area largely determines cistern reliability, social cooperation plays a crucial role in sustaining access to water. By highlighting the interplay between infrastructure and collective action, this research offers new socio-hydrological insights into community resilience in drought-prone regions.

12. “Data-Driven Detection of Climate–Streamflow Dependencies and Multi-Year Hydrological Persistence in Brazilian Reservoir Systems”
by Leonardo A. F. Mendoza, Antonio G. G. Lima, Harold D. de Mello, Jr., Maria Elvira P. Maceira, Albert C. G. Melo and Marco A. C. Pacheco
Water 2026, 18(12), 1499; https://doi.org/10.3390/w18121499
Available online: https://www.mdpi.com/2073-4441/18/12/1499

Cover story: This study investigates how large-scale climate variability influences streamflow dynamics and hydrological persistence in two major Brazilian reservoirs, Serra da Mesa and Três Marias. Using climate indices, temporal filtering, statistical analyses, and forecasting experiments, this research reveals persistent low-frequency climate–streamflow relationships and contrasting hydrological response timescales between the two basins. The cover image summarizes the study framework, highlighting the reservoirs, the climate modes analyzed, and the low-frequency hydrological signals associated with streamflow persistence and predictability.

Interview with Dr. Zhenyao Wang—Winner of the Water Best PhD Thesis Award


Water
(ISSN 2073-4441) is proud to confer the Best PhD Thesis Award upon Dr. Zhenyao Wang.

Dr. Wang received his PhD from the University of Technology Sydney. His research interests focus on waste and biomass valorization, advanced wastewater treatment, machine learning-assisted process optimization, and environmental sustainability assessment.

1. Congratulations on winning the Water Best PhD Thesis Award! Could you start by briefly introducing yourself and elaborating on your doctoral research topic?

Hello everyone, my name is Zhenyao Wang. I received my PhD from the University of Technology Sydney, Australia, and I currently work at the Department of Environmental Science and Engineering at Macau University of Science and Technology. My research mainly focuses on waste and biomass valorization, advanced wastewater treatment, machine learning-assisted process optimization, and environmental sustainability assessment.

My PhD research was titled “Advancing Sludge Management for Sustainability through Lignosulfonate.” The basic idea was to use lignosulfonate, a by-product from the pulp and paper industry, to improve sewage sludge treatment. It can promote sludge hydrolysis and organic matter release, which creates more opportunities for energy and resource recovery. We also found that the digested sludge had the potential to promote plant growth, making its land application more promising.

2. How did you first learn about the Water Best PhD Thesis Award, and what value do you believe such academic awards bring to early-career researchers?

I first heard about the award from one of my colleagues, who encouraged me to apply. As an early career researcher, this award means a lot to me. I see it as both a recognition of what I achieved during my PhD and an encouragement for what comes next. It gives me more confidence and motivation to continue developing my research and exploring new ideas. I think this kind of recognition is especially meaningful for young researchers because it reminds us that the work we are doing is valued and encourages us to keep moving forward.

3. How do you feel about receiving this prestigious recognition for your doctoral work? As this year’s award recipient, and are there any people you would like to thank or any feelings you wish to share?

I feel very honored and grateful to receive this award. I am sincerely grateful to everyone who supported, guided, and helped me throughout my PhD journey. I am also especially thankful to my parents and family for their constant support, understanding, and encouragement.

I would also like to thank Water and the award committee for this recognition. For me, this award is not only a recognition of my PhD work, but also a great motivation to keep moving forward and continue pursuing meaningful research.

4. During your PhD research, what was the most significant challenge you encountered, and what approaches did you take to overcome it?

I think one of the biggest challenges was moving into a completely new research area. Before my PhD, I mainly worked on microalgae, so many things were new to me. For example, I had never used a BMP system before. So I contacted the manufacturer and spoke with their engineers several times by phone and email. After a lot of troubleshooting and practice, I eventually became comfortable using it independently. I think this experience taught me to be proactive and always try to find a solution when I face a new problem.

5. Looking back on your entire doctoral journey, which experience or moment left the deepest impression on you, and why?

I think what impressed me most was the guidance I received from my supervisors. They taught me how to write, revise, and submit research papers, but more importantly, they trained me to think scientifically and systematically. This gradually changed the way I approach research problems and helped me become a more independent researcher. I think that is one of the most valuable things I gained from my PhD journey.

6. If you were to summarize your precious PhD journey in one sentence, what would it be?

If I had to summarize my PhD journey in one sentence, I would say: “Where there is a will, there is a way”. There were many challenges along the way, but I believe that with determination and persistence, we can always find a way forward.

7. How do you plan to build on and further advance your existing research in the future? What are your long-term academic and career goals?

Looking ahead, I would like to continue working in biomass and waste valorization and explore better ways to recover energy and valuable resources from waste. I also hope to integrate machine learning and sustainability assessment into my research to make these processes more efficient and practical. In the long term, I hope to keep doing meaningful research, train young researchers, and make a real contribution to environmental sustainability.

8. Based on your rich doctoral experience, what valuable suggestions would you offer to current PhD students who are pursuing their academic studies?

I think facing challenges during a PhD is completely normal. My advice is to have the courage to face them and the persistence to overcome them. Do not be afraid of difficulties or failure. Keep exploring, keep learning, and keep moving forward. As long as you stay determined and never give up, I believe your efforts will eventually pay off.

We would like to extend our sincere gratitude to Dr. Zhenyao Wang for accepting our interview invitation and sharing insights into his PhD journey. We wish him every success in his future research endeavors.
