Personal Page:

My curent primary research interest is in developing statistical methods for the analysis of observational data, mostly from eletronic medical records. I have conducted research in statistical methods dealing with confounding with missing data. I have

been involved in research projects in pharmacoepidemiology for drug safety and public health.  I have extensive experience working with a team of medical researchers, biostatisticians and data managers on various database and clinical studies. I am the project lead and co-lead of two industry funded projects on statistical methodology of confounding control and characterization of hypentension patients and management.  I am the Core Leader for the Biostatistics Core of the 2012 Merck-Regenstrief collaboration. My other interests include statistical computing, non- and semi-parametric regression, clinical trials and bioinformatics.
