Research Overview

I see physics as the ultimate way of understanding nature and appreciating its deepest beauty. In my personal opinion, the field in which present day science faces its greatest challenges is the description and understanding of biological processes. In most physical fields we have a fair understanding of at least the first few levels of detail and approximation. In biology on the other hand, we are far from obtaining a clear picture of what truly controls and directs even the simplest cell, let alone an organism. Thus after a few years in somewhat ‘mechanical’ physics (ballistics and penetration dynamics), I have turned to the study of live cell biophysics.
My research is focused around the question of chromatin organization in the cell nucleus. This project demands the incorporation of in vivo fluorescent microscopy with advanced analysis of stochastic data and analytic physical modeling. For me, this combination of messy, ‘hands on’ biology together with ‘clean’ physical modeling is a modern day manifestation of basic science.
