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 an associate professor of anesthesiology in the Department of Anesthesiology. I am also the biostatistician in the Eastman Institute for Oral Health and the Department of Urology at URMC. My research interests include multivariate survival analysis, empirical processes theory, longitudinal data analysis and statistical methods in epidemiology and clinical trials.
