Our People


Tracy Onega, The Professor

Tracy Onega, PhD, MA, MS, is an associate professor, and interim division director, of biomedical data science in the Dartmouth Geisel School of Medicine. She focuses on population-based approaches to optimizing how healthcare resources are allocated across populations and how the spatial distribution of services can impact treatment and outcomes. With a background in geography and health informatics, her major interests focus on access to cancer care, geospatial methodologies; and how geoinformatics can lead to better use of healthcare resources.

Jennifer Alford-Teaster, The Deputy

Jennifer Alford-Teaster, MA, MPH, is a geospatial research project director in the Department of Biomedical Data Science at Dartmouth College. Jennifer has combined her advanced training in applied geography and public health to provide analytic research support on projects utilizing Geographic Information Systems (GIS).


Dr. Anna M. Adachi-Mejia

Anna M. Adachi-Mejia, Ph.D.
Dr. Adachi-Mejia is the Director of the Health Promotion Research Center at Dartmouth (HPRCD) and an Associate Professor at the Geisel School of Medicine at Dartmouth. The overarching aim of her research is cancer prevention with the long-term goal to inform interventions to promote healthy living in healthy environments. Her work focuses on the contributions of community and the built environment to three sets of risk behaviors: smoking, healthy eating, and activity (e.g., sleep, sedentary, physical, media/screen time). She has developed innovative approaches to data collection from humans (youth and adult) to determine the influence of the micro (e.g., bedroom) and macro (e.g., community) environment on these three sets of behaviors. This research leverages her multidisciplinary training and collaborations to apply novel strategies to measure both human behavior and health outcomes.

Dr. Erika Moen

Erika Moen, Ph.D., M.S. is an Assistant Professor in the Department of Biomedical Data Science in the Dartmouth Geisel School of Medicine. The overarching goal of Erika’s research program is to use biomedical informatics approaches to optimize cancer care delivery with the overall goal of improving patient outcomes. A primary focus of her work uses network analysis to study how physicians work together and how they may influence each other to adopt novel cancer tests and treatments into clinical practice. Her research leverages her interdisciplinary training in cancer biology and translational science to help bridge the process of taking biomedical innovation from the “bench to the bedside”.

Dr. Fahui Wang

Fahui Wang, Ph.D. James J Parsons Professor, Department of Geography and Anthropology, Louisiana State University, Baton Rouge, LA, USA. Dr. Wang has extensive experience in applications of Geographic Information Systems (GIS) and spatial analysis in health studies, with primary interests in analysis of health care allocation and accessibility, their impacts and policy mitigation. He is the author of “Quantitative Methods and Applications in GIS” (Taylor & Francis, 2006), “Quantitative Methods and Socioeconomic Applications in GIS” (2nd ed., Taylor & Francis, 2015) and over 100 refereed articles across various disciplines (health studies journal outlets include Cancer, Medical Care, Health Services Research, Health & Place, I J Health Geographics, J Medical Systems). He has served multiple panels of NIH Scientific Review Groups (HSOD, SBIR and HDEP) since 2006.
