Ms. Soumya Gupta completed her Master's degree (M.Tech) in Biotechnology from Vellore Institute of Technology, India, in 2021 and her Undergraduate degree (B.Tech) in Biotechnology from Graphic Era University, India, in 2019. She is currently pursuing her PhD under a UNITA-FCT Fellowship between the University of Beira Interior, Portugal, and the University of Zaragoza, Spain, and her research work focuses on the use of dark and photofermentation techniques for the production of hydrogen.

Annabel Fernandes graduated in Chemistry—Scientific Branch from the Faculty of Sciences, University of Portoin in 1999, and earned her MSc and Ph.D. in Chemistry from the University of Beira Interior (UBI) in 2003 and 2014, respectively. Between 1999 and 2011, she developed professional activity in industry, mainly in the area of quality and environmental management systems, according to ISO 9001 and ISO 14001. In 2012, she started an FCT-financed Ph.D. program (SFRH/BD/81368/2011) under the theme “Electrochemical treatment of sanitary landfill leachates” and, between 2015 and 2018, she benefited from a postdoctoral grant, financed by FCT (SFRH/BPD/103615/2014), under the theme “Sustainable treatment of effluents from urban wastes management”. She has been a researcher at UBI, FibEnTech Research Unit since 2018, and develops her research in the Chemistry Department. She develops studies in the field of environmental electrochemistry applied to the degradation of persistent organic pollutants present in real and simulated effluents, and also applies/develops analytical methodologies for the monitoring of environmental parameters during the treatments. More recently, she has been focused on the study and development of bioelectrochemical processes, aiming for sustainable treatment solutions in a circular economy approach.

Ana Lopes is an Associate Professor at FibEnTech-UBI, Department of Chemistry, University of Beira Interior. Ana Lopes received an MSc in Chemical Engineering at IST, Technical University of Lisbon in 1986, and earned a Ph.D. in Chemistry from the University of Beira Interior in 1998. Ana Lopes is also a member of the International Society of Electrochemistry. Presently, Ana Lopes’s work deals mostly with the preparation of metal oxides, namely from the perovskite family, with environmental purposes, and with the application of electrochemical techniques to solve environmental problems.

Laura Grasa is an Associate Professor at the University of Zaragoza (Spain). She has a Bachelor’s Degree in Veterinary Medicine and earned her Ph.D. in Physiology and Pharmacology in 2006, from the University of Zaragoza. She also has a Master’s Degree in Advanced Bioinformatic Analysis from the Pablo de Olavide University (Spain). Her research focuses on the study of microbiota–intestine interactions in intestinal pathologies, such as inflammatory bowel disease or antibiotic-induced diarrhea. She has great experience in cell and animal models, molecular studies, and bioinformatics analysis. She investigates the properties of food ingredients in improving intestinal health by modulating the motor function, immune system, or intestinal microbiota. Her other research includes the anticancer properties of organometallic compounds and carbon nanoparticles, using cell lines and animal models of colon cancer. She is a fellow of the United European Gastroenterology and the Spanish Society of Microbiota, Probiotics and Prebiotics.

Dr. Jesús Salafranca is a Full Professor at the Escuela de Ingeniería y Arquitectura (EINA) at the University of Zaragoza. He obtained a doctorate in Chemical Sciences, specializing in Analytical Chemistry, at Zaragoza's University in 1997. He has many contributions to national and international conferences. His research interests include food packaging, analysis of environmental matrices, and, recently, the production of biohydrogen by fermentative means. He has produced about 40 papers in high-quality international journals reported in the Web of Science and Scopus, resulting in an h-index of 21, the publication of 3 book chapters, and more than 50 conference communications, most of them international.
