Lauren Hunt is a postdoctoral research associate in the Department of Behavioral and Social Sciences. Her research focuses on agricultural decision-making and behavior, particularly in the context of climate change, including producer adaptation and mitigation strategies, perceptions of climate impacts, and the efficacy of climate programs across diverse agricultural systems. She uses interdisciplinary, mixed-methods social science and geospatial approaches to inform policy and decision support for sustainable and resilient rural communities and agroecosystems. Dr. Hunt was previously a Gund Institute for Environment postdoctoral fellow and research associate at the University of Vermont. She earned her PhD in Ecology, Evolution and Behavior and Human-Environment Systems from Boise State University. She also holds an MSc in Entomology and a BSc in Biology from the University of Maryland.

Jeung Hyun Kim is a postdoctoral research associate at the Center for Gerontology and Healthcare Research at Brown University. Her research interests lie at the intersection of aging and the family life course, as it pertains to the psychological and cognitive well-being of older immigrants and their ethnic communities. Kim’s work offers comparative perspectives on race and ethnicity to understand the sociocultural origins of health inequality. Currently, she is investigating the migration of Puerto Rican older Medicare beneficiaries who suffer from dementia and other chronic diseases. Kim developed her research interests from her master’s thesis in Development Studies at the University of Cambridge where she shed light on the transnational movement of migrants from the less developed countries to the U.S. Building on the topic, she completed her doctoral research in the Department of Sociology at Syracuse University.

William (Bill) Nardi holds an Sc.M. and Ph.D. from Brown University. His postdoctoral research appointment is in the department of Behavioral and Social Sciences and the Mindfulness Center. He is interested in patient-oriented research for the development of comprehensive, integrative treatments for comorbid substance use and anxiety. Specifically, his work focuses on designing and testing mobile health applications as adjunctive therapies to primary substance use treatments utilizing mixed methods research. 

Chanda Phelan is interested in researching human-computer interaction focused on the opportunities and challenges of integrating technology into substance use disorder (SUD) treatment, and understanding how technology is used during the recovery journey. She completed her Ph.D. at the University of Michigan and focused on the opportunities, threats, and strategies for technology in SUD.

Dr. Vinicius Neves earned his MD in Brazil and completed a Master of Science in Health Psychology at University College London (UCL). He is currently a Postdoctoral Research Associate at the Mindfulness Center at Brown University School of Public Health, working under an NIH-funded project.

He is particularly interested in integrative approaches that bridge psychology, cardiology, and public health.

Dr. Jue Yang is a postdoctoral research associate in the Social EPI Lab at the Brown University School of Public Health's Center for Health Promotion and Health Equity. She received a Ph.D. in Geography from the University of Georgia and M.A. in Geography from the University of Florida. Her research focuses on associating, understanding, and measuring environment and children's health. Jue is also interested in employing spatial analysis methods to tackle various health-related issues, such as healthcare accessibility; health crisis affecting human mobility; etc. In the Social EPI Lab, she focuses on studying how exposure to green spaces influences children's sleep and mental health using geographical data.

Dr. Shuyuan Yang is a Postdoctoral Research Associate in the Department of Epidemiology at Brown University. He received his Ph.D. in Epidemiology from The Chinese University of Hong Kong. His current research focuses on pharmacoepidemiology and causal inference, with an emphasis on evaluating the real-world effectiveness and safety of medications for chronic disease prevention and management. In particular, he applies tailored target trial emulation frameworks to study clinical outcomes across patients with diverse clinical profiles. He is also interested in advancing transportability and generalizability methods that synthesize evidence from multiple data sources to improve the validity of treatment effect estimates in the target populations of interest.

Dr. Dongliang Zhang is a Postdoctoral Research Associate in the Department of Biostatistics.
