Lee Kennedy-Shaffer Assistant Professor of Mathematics and Statistics
Lee Kennedy-Shaffer received his BS in mathematics from Yale College and his PhD in biostatistics from the Harvard T.H. Chan School of Public Health. He joined the Vassar faculty in 2020 after a brief postdoc with the Center for Communicable Disease Dynamics at Harvard. His research interests include the role of clustering and correlation in clinical trials and the design of clinical trials and epidemiologic studies for infectious diseases. This has led to various work on study design in the COVID-19 pandemic, including estimating epidemic trajectories and accounting for overdispersed transmission. He is also interested in the history of statistics, specifically its role in regulation and the law and the role of eugenics in the development of statistics.
