I am an Associate Professor in the Department of Biostatistics at Columbia University Mailman School of Public Health.  My primary research interests lie in survival analysis, longitudinal data, and statistical learning. I have been developing statistical methods to address the challenges posed by complex datasets from electronic health records (EHRs), observational studies, clinical trials, and the integration of multiple data sources. My CV can be found here.
