4. Scientific Presentations
Panel 1: Animal Health and One Health
Dr. Andrew Hoffman, Dean, School of Veterinary Medicine at the University of Pennsylvania, presented his talk on “The Criticality of Animal Science to One Health”. He emphasized ‘Animal Science’ as an indispensable pillar of One Health, especially in addressing grand global challenges like food insecurity, undernourishment, and food poverty. Drawing on global and regional data, Dr. Hoffman explained how food security remains tightly linked to animal health, especially in low- and middle-income countries where livestock and poultry are central to daily nutrition and economic survival. He highlighted that many food production systems suffer from inefficient yields due to preventable animal diseases such as diarrhea, pneumonia, and reproductive disorders. He stressed that broad food insecurity and poverty cannot be effectively mitigated without addressing endemic livestock health issues. Dr. Hoffman noted that while current One Health strategies focus well on zoonoses and vector-borne diseases, there is an excellent opportunity to better include animal production and welfare in the overall approach to health. He emphasized that integrating animal science into One Health will strengthen public health preparedness and improve sustainable food systems. Dr. Hoffman concluded by advocating for a robust regional and national One Health infrastructure built on veterinary leadership and data-driven decision-making that includes animal production as a core component.
Dr. Erika Ganda, Assistant Professor in the Department of Animal Science at Penn State University, presented an engaging presentation titled “Microbiomes Linking Food Systems, Animals, and Human Health”. Trained as a veterinarian in Brazil, Dr. Ganda’s career has evolved through a global and interdisciplinary lens, spanning animal health, food safety, antimicrobial resistance (AMR), and microbiome-based interventions. She emphasized that as global populations grow and farmland remains finite, microbiome stewardship will be critical to improving agricultural sustainability and public health outcomes. She highlighted Salmonella dublin as an example of a One Health challenge, as it is an emerging zoonotic bacterial pathogen capable of causing serious, drug-resistant infections in humans and animals. Through surveillance and genomic analyses, her team found that S. Dublin isolates from cattle, humans, and food were often genetically identical, confirming transmission across sectors. Her work revealed alarming AMR patterns, with nearly a third of S. Dublin isolates showing resistance to several antibiotic classes. Dr. Ganda closed by advocating for a balanced perspective that promotes integrated, data-driven solutions to shared health threats across species and systems.
Dr. Stephen Cole, Assistant Professor and Director of the Clinical Infectious Disease Laboratory at the University of Pennsylvania, delivered a presentation titled “Bad Bugs and Good Pugs: Antimicrobial Resistance in Companion Animals”, highlighting the growing concern of antimicrobial resistance in pets, particularly the emergence and transmission of carbapenem-resistant Enterobacteriaceae (CRE). These “last resort” drug-resistant bacteria have emerged in pets despite minimal veterinary use of carbapenems, highlighting their potential for silent spread and community transmission. Dr. Cole shared a landmark case of a Great Dane infected with carbapenemase-producing E. coli, which marked the start of an outbreak in a veterinary hospital. Genomic analysis revealed the same resistant strain in other animals, environmental surfaces, and staff, highlighting silent colonization and challenging detection. His lab has since provided infection control consultations to over 20 veterinary hospitals across the U.S. and is leading efforts to track the spread of these organisms using whole-genome sequencing. Dr. Cole advocated for enhanced antimicrobial stewardship, better diagnostic and genomic tools, and the inclusion of veterinary facilities in national AMR surveillance frameworks. He closed by reminding the audience that pets are deeply embedded in human lives and built environments, and therefore must be included in all strategies to address the growing global AMR crisis.
Dr. Julie Ellis, Wildlife Ecologist, Associate Director of the Institute for Infectious and Zoonotic Diseases (IIZD) at Penn Vet, presented “Integrating Fish and Wildlife Health Priorities into the 2025–2035 Pennsylvania Wildlife Action Plan,” highlighting a landmark effort to formally incorporate wildlife health into statewide conservation planning for the first time. Developed in partnership with the Pennsylvania Game Commission and the Fish and Boat Commission, the updated Wildlife Action Plan now includes a comprehensive assessment of health threats to over 600 species of greatest conservation need, including mammals, birds, amphibians, reptiles, fish, and freshwater mussels. Dr. Ellis and her team conducted literature reviews, expert surveys, and interviews to identify key threats, ranging from viruses, fungi, and parasites to industrial pollutants, and wastewater contaminants. These threats are often exacerbated by climate change and disproportionately affect species already facing population pressures. For instance, birds are vulnerable to heavy metals and avian viruses, amphibians face devastating fungal infections like chytridiomycosis, and reptiles are impacted by pesticide exposure and emerging diseases. Dr. Ellis stressed that effective biosecurity practices, including pathogen screening prior to animal translocation, disinfection of field gear, risk assessments, and vaccination strategies are critical tools for mitigation. She also emphasized the need for improved surveillance systems, rapid diagnostic tools, and public outreach to address environmental contaminants and wildlife diseases. Dr. Ellis concluded with a call to give wildlife a full seat at the One Health table, ensuring that environmental and ecological health considerations are prioritized alongside human and animal health in future planning.
Panel 2: Plant and Ecosystem Health and One Health
Dr. Melissa Bilec, Special Assistant to the Provost for Sustainability and Co-Director of the Mascaro Center for Sustainable Innovation at the University of Pittsburgh, presented “Integrating Systems Thinking & Sustainable Ecosystems” with a compelling call to adopt holistic frameworks for addressing complex ecological and health challenges. She introduced systems thinking as a vital interdisciplinary approach that enables us to understand relationships among environmental, health, and societal systems rather than viewing components in isolation. Through this lens, she emphasized the importance of circular thinking, building trust across disciplines, and co-developing tools that reflect real-world interconnectedness. A core focus of her talk was Life Cycle Assessment, a quantitative method that evaluates the environmental and health impacts of products and systems from raw material extraction to end-of-life. Dr. Bilec identified key barriers to cross-sectoral collaboration in the One Health space, such as disciplinary silos, persistent data gaps, and misaligned policies, and pointed to opportunities through co-design with affected communities and data-driven policymaking. She urged the One Health community to embrace systems-level tools to anticipate unintended consequences, set measurable sustainability baselines, and advance long-term investments in ecosystem health as preventative health care. Dr. Bilec concluded by encouraging researchers and institutions to shift from isolated work to collaborative partnerships, emphasizing that the complexity of today’s challenges demands integrated, adaptive, and forward-looking approaches.
Dr. Mary Ann Bruns, Professor Emerita of Soil Microbiology at Penn State University, presented “Resilient Soil-Plant-Microbiome Systems for Long-Term Human and Animal Health,” emphasizing that microbiomes are central to ecosystem function and the health of plants, animals, and humans. She explained how plant–soil–microbiome partnerships are essential for land management and agricultural sustainability. Soil microbiomes play a key role in nutrient cycling, pathogen suppression, and improving plant stress tolerance, especially during drought. Bruns highlighted that maintaining soil organic matter is crucial to supporting microbial life, with healthy soils requiring at least 100 times more carbon than the microbial biomass they support. Practices such as conservation tillage, cover cropping, and minimizing physical soil disturbance help protect fungal networks and organic inputs vital to microbial health. These healthy partnerships reduce soil and nutrient loss, improve soil structure, and decrease dependence on synthetic fertilizers. Bruns underscored the risks of ignoring soil health, citing historical and ongoing examples like the Dust Bowl and nutrient-driven dead zones. She concluded by framing soil and microbiome stewardship as one of the core One Health priorities foundational to long-term human, animal, and environmental well-being.
Dr. Deah Lieurance, Assistant Professor of Invasive Species Biology and Management at Penn State, presented “Enhancing Biosecurity by Identifying Invasive Species Threats, Pathways, and Impacts,” emphasizing the critical role invasive species play as one of the top global drivers of biodiversity loss. She underscored their immense ecological and economic impact, citing a global annual cost of over $423 billion, with the U.S. alone incurring nearly $20 billion in damages, primarily in agriculture and forestry. Dr. Lieurance introduced the invasion management curve, illustrating that early detection and rapid response are far more cost-effective than managing widespread invasions. She highlighted how invasive species also intensify wildfire risk. Her research focuses on proactive strategies like horizon scanning and rapid risk assessment to identify high-risk species and prioritize management efforts. She also detailed the importance of pathway management and biosecurity measures, from pre-border cargo inspections and detector dogs to public outreach campaigns like “Don’t Move Firewood.” Dr. Lieurance concluded by advocating for a “One Biosecurity” framework that promotes cross-sector collaboration among human, animal, plant, and environmental health sectors, aligning One Health principles with global and local biosecurity strategies.
Dr. Justin Brown, Assistant Teaching Professor at Penn State University, presented “A One Health Approach to Understanding Disease Risks in Wild and Domestic Canids in Pennsylvania,” focusing on gastrointestinal (GI) parasitism and its implications for animal and human health. He highlighted GI parasites as a persistent challenge in companion animals, noting their potential zoonotic risks despite routine prevention and diagnostics. Dr. Brown introduced the KeyScreen PCR assay as a multiplex pathogen detection tool to detect over 20 GI parasites, including drug-resistant hookworms and zoonotic Giardia strains. His team applied this technology to analyze fecal samples from wild canids (coyotes, foxes), hunting dogs, and companion dogs, generating comparative data across species. Their findings showed significantly higher parasite prevalence in wild canids, including Echinococcus spp. The research revealed that domestic dogs, while not currently positive for Echinococcus, share overlapping ecological spaces and could become reservoirs. Dr. Brown emphasized the importance of bridging communication gaps between veterinary, public health, agriculture, and wildlife sectors using comprehensive diagnostic data to inform integrated surveillance and response efforts.
Robin Eng, Wildlife Ecologist with the Pennsylvania Department of Conservation and Natural Resources, delivered a talk titled “Ecological Communities Drive Ecosystem Restoration: Considering Functional Interactions and Holding Space for the Undiscovered.” Eng emphasized that ecosystem restoration is inherently complex, adaptive, and context-specific, requiring flexibility and responsiveness to changing conditions. She described ecological communities as dynamic, interconnected systems where species interact with one another and their environment in both direct and subtle ways. Restoration must be seen as a collaboration with non-human partners such as soil microbes, fungi, plants, and animals, who are active participants in shaping healthy ecosystems. She also introduced the importance of recognizing functional interactions, such as physical habitat structures that support wildlife behaviors or soil microbial processes that enhance nutrient cycling. She encouraged adaptive management that responds to evolving site conditions and emphasized that biodiversity contributes to ecological richness and improves ecosystem stability. Dr. Eng emphasized the importance of making room for the unknown, recognizing that many factors behind ecosystem health are still undiscovered but crucial for long-term resilience.
Panel 3: Human Health and One Health
Dr. Maureen Lichtveld, Dean of the School of Public Health at the University of Pittsburgh, presented “One Health as a Precision Public Health Strategy,” emphasizing the need to shift focus from individual genetics to the broader environmental, social, and ecological determinants that account for the majority of public health risk. She stated that ‘precision public health’ requires fine-tuned, local data to inform targeted interventions, and that One Health offers a powerful framework for integrating such data across human, animal, and environmental sectors. She emphasized that community-engaged science, grounded in local knowledge, is essential for building public trust and ensuring culturally relevant and effective public health interventions. Dr. Lichtveld further discussed global case studies, including mercury contamination from gold mining, underscoring the importance of risk-benefit analyses that include cultural, geographic, and social context. She concluded by emphasizing that predictive, preventative approaches grounded in community data and One Health collaboration will be critical to building healthier, more resilient populations while reducing long-term healthcare costs.
Dr. Suresh Kuchipudi, Professor and Chair of the Department of Infectious Diseases and Microbiology at the University of Pittsburgh, presented “Emerging Zoonotic Viruses and Impacts on Human Health,” emphasizing the urgent need for integrated One Health approaches in managing infectious disease threats. He described that pathogen emergence can be affected by factors such as land use changes, climate change, deforestation, urbanization, and population shift. Modern travel and trade further enable pathogens to move across borders in real time, making traditional surveillance approaches inadequate. Using the example of the H5N1 clade 2.3.4.4b virus, Dr. Kuchipudi illustrated how a virus once considered avian-specific is now circulating among marine mammals, dairy cattle, and humans, demonstrating the complexity of multi-host, multi-directional spillover. Dr. Kuchipudi further emphasized that the integrated cross-sectoral collaboration is hindered by institutional silos, fragmented systems, sector-specific funding and training, regulatory complexity, and data privacy concerns. He proposed ‘Precision One Health’ as a data-integrated framework that can potentially use artificial intelligence, cross-species surveillance, and multidisciplinary science to predict, prevent, and control emerging zoonoses.
Dr. Iulia Vann, Director of Allegheny County Health Department, presented “Hot Zones: How Climate Change is Rewriting the Rules of Public Health,” highlighting the urgent need to reframe public health through a climate-informed, One Health lens. She described how climate change is accelerating environmental disruptions such as wildfires, flooding, and vector-borne disease outbreaks, increasing human health risks and disproportionately impacting communities. Dr. Vann advocated for climate-resilient public health strategies that move beyond reactive responses and instead emphasize integrated surveillance systems, green infrastructure, mobile healthcare delivery, and the development of community resilience hubs. She underscored the importance of cross-sector collaboration and embedding One Health principles into urban and regional planning processes to address systemic inequities and prepare for future threats. Vann concluded that although climate change has created “hot zones” of vulnerability, addressing them effectively will require collaborative, equitable, and proactive public health strategies.
