Research Interests

I received my PhD in Statistics from the University of Rochester in 2002.  Currently I'm an associate professor of biostatistics in the Department of Biostatistics and Computational Biology and a professor of anesthesiology in the Department of Anesthesiology. I am also the biostatistician and Co - Director in the Department of Dentistry.  My research interests include multivariate survival analysis, empirical processes theory, longitudinal data analysis and statistical methods in epidemiology and clinical trials.
