Associate Professor of Biostatistics and Epidemiologic Methods
Ph.D., 2006, Harvard University
B.S., 1999, Yale University
I am an associate professor with joint appointment in the departments of Epidemiology and Biostatistics at the Harvard School of Public Health. My primary area of interest is in semi-parametric efficiency theory with application to causal inference, missing data problems, statistical genetics and mixed model theory. In general, I work on the development of statistical and epidemiologic methods that make efficient use of the information in data collected by scientific investigators, while avoiding unnecessary assumptions about the underlying data generating mechanism. Recently, my research with other collaborators has contributed new robust and efficient methods for the estimation of gene-environment statistical interactions in their effects on causing disease.
