My research interests are in probability theory and its
My thesis work concentrated on
branching processes and their asymptotics, the motivation
coming from a model for macroevolution.
Some of my current research is in analysis of
stochastic models related to population biology.
I am also involved in a research
project on stochastic models for intracellular reaction
