The Team

Meet the folks behind the Michigan COVID-19 Tracker

Jon Zelner

Jon is an Assistant Professor in the Department of Epidemiology and the Center for Social Epidemiology and Population Health at the University of Michigan. Dr. Zelner is an infectious disease epidemiologist whose research is focused on the intersection of social and biological mechanisms in spatiotemporal patterns of infectious disease transmission. His work covers a broad range of infections with a primary focus on respiratory infections including tuberculosis, influenza and COVID-19, as well as vaccine-preventible diseases and diarrheal disease.

Nina Masters

Nina is a doctoral candidate in Epidemiology at the University of Michigan. She did her MPH in Global Health Epidemiology at the University of Michigan and her bachelors in Chemistry and Materials Engineering at Princeton University. Her dissertation research focuses on spatial transmission models of infectious diseases, the impact of clustered non-vaccination on outbreak risk, and the evolution of vaccine hesitancy. She is passionate about science communication and seeks to make epidemiologic research accessible with her blog: knowyourvax.com

Rob Trangucci

Rob is a PhD candidate in the Statistics department at the University of Michigan. His current research focuses on developing novel Bayesian statistical methodology for problems in epidemiology, and creating tools to understand how modeling assumptions impact inference. He has also done research in survey methodology. He got his Master’s in Quantitative Methods in the Social Sciences from Columbia University and his BA in Physics from Bucknell University.

Paul Delamater

Dr. Paul Delamater is an Assistant Professor in the Department of Geography, a Faculty Fellow at the Carolina Population Center and Sheps Center for Health Services Research, and an Associate at the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill. Dr. Delamater has particular interest in research relating to the spatial components of health care access and utilization, as well as disease modeling. He employs geographic information systems (GIS) and statistical/spatial analysis to better understand population health issues. His recent research has focused on understanding childhood vaccination, herd immunity, and vaccine-preventable diseases in the United States.

Ramya Naraharisetti

Ramya is a doctoral student in the department of Epidemiology at the University of Michigan. She received her Masters of Science in Global Health from Harvard University and her Bachelors of Science in interdisciplinary social sciences from Michigan State University. Her research focuses on social inequality and the spread of infectious disease both domestically and in the Global South. She utilizes spatial analyses, hierarchical modeling and mathematical models to advance our understanding of these complex processes.

Alex Cao

Alex is a data scientist at the University of Michigan with CSCAR (Consulting for Statistics, Computing & Analytics Research). He helps researchers with their data science problems and teaches people about data science via workshops. He used to do research with surgical robots and NASA but now he makes predictive models and interactive data visualizations.

Kelly Broen

Kelly is a doctoral student in the department of Epidemiology at the University of Michigan. She received her Masters of Public Health from the University of Michigan in epidemiology and her Bachelors of Science in Human Health and Quantitative Sciences from Emory University. She is interested in spatial epidemiology and infectious diseases.

Ryan Malosh

Dr. Malosh is an Assistant Research Scientist at the University of Michigan School of Public Health. He is currently leading studies of herd immunity resulting from influenza vaccination of household contacts. Additional research interests include respiratory virus epidemiology and prevention, vaccine uptake, and social determinants of infectious disease. He is currently working on studies of COVID-19 in the household and community settings, with a particular focus on non-pharmaceutical interventions.

Stephanie Choi

Stephanie is a UI/UX designer. She is interested in making accessible designs so a diverse group of people can use the services and sites she creates. She received her Master of Science from the University of Michigan School of Information. Her portfolio site, choisteph.github.io, features some of the projects she has worked on.
