I joined the Biostatistics faculty at Emory in 2005, as the Rollins Assistant Professor. My methodological research has been mainly focused in the area of survival analysis. Specially, I have worked on semi/competing risks problems in various aspects. Recently I have been interested in?methodology related to varying-effect survival models. My research effort in this direction is now partially?supported by a NSFgrant.

I have also collaborated on several other biostatistical methodological grants in the areas of agreement study and the analysis of epidemiological reproductive and environmental?data. My other collaborations include providing statistical support/consulting to medical investigators in the areas of epilepsy, diabetes and cancer, and researchers in health economics.
