Assistant Professor of Biostatistics
Biography
Kendra Plourde earned her PhD in Biostatistics at Boston University in 2020, and joined the Yale School of Public Health faculty in 2022 as an Assistant Professor of Biostatistics after completing a postdoc at Yale. Her methodological research interests are in the design and analysis of observational studies and randomized controlled trials with correlated data, for example, longitudinal studies, cluster randomized and stepped wedge designs with complex sources of clustering, and clinical trials with multivariate outcomes. Her collaborative research interests are in studies of Alzheimer's disease and related dementias and aging. Kendra is also a member of the Yale Center for Analytical Sciences and a collaborator with the Yale Program on Aging.
