Area of Research: Structural dynamics of biomolecules

The atoms and molecules in a cell are always jiggling, dancing and bumping into each other and occasionally carrying out a specific reaction or a process. This forms the lifeline of all organisms. Hence it is important to understand how exactly this is choreographed. The most sophisticated experimental technology is only just beginning to give us a glimpse of this intricate dance but at a very coarse level. Computer simulations of this dance are increasingly providing much needed atomistic details. The general interest of our group is to gain novel insight into biology from the computer simulations of such events. Such methods can be used to both understand the dances and what happens when things go wrong that lead to a disease such as cancer. Using those information one can start designing drugs in a rational manner. Right now the p53-pathway and Bcl2 family are two primary areas of focus, where both are promising areas of cancer therapeutics. We work in a truly interdisciplinary manner and so students/postdocs coming from various disciplines e.g. Chemistry, Physics, Biology, Computer Science etc. can contribute to our laboratory with their own domain of expertise and can expand knowledge in other areas.
