"The way to get good ideas is to have a lot of ideas, and throw away the bad ones."

Introduction

I am a Post-doctoral scholar in Prof. Michele Parrinello's group at Department of Chemistry and Applied Biosciences, ETH. Prior to this I obtained my PhD from Department of Applied Physics & Materials Science, Caltech. During my PhD and currently, my interest has been in developing Statistical Mechanics based enhanced sampling methods for simulating complex biological and engineering materials, especially at laboratory time scales, using classical and quantum frameworks. I then apply these tools to study a range of problems, such as but not limited to:

How much time does a drug take to unbind from its host protein, and what pathway does it take?
What morphologies do deposited adatoms adopt on a thin film, and in how much time?
How do dislocations nucleate? How long do they take to appear and when, where and why do they disappear?

Please check out the Publications page for a detailed list of publications.

News:

(February 2014) A new revised, faster update of the long-time scale MD code SISYPHUS should be up by end of March 2014.

(Conference announcement) We are organizing a CECAM workshop on 'Long time dynamics from short time simulations' in Lugano, Switzerland from March 12-14 in 2014. Please visit the conference website for more details including list of speakers and how to apply.

(November 2013) "From metadynamics to dynamics" published in Physical Review Letters, where it has been chosen as one of the spotlight articles in that issue. Using this, it is now possible to recover real time from Metadynamics simulations. The protocol is simple, and can be used with many MD codes of your choice via the Metadynamics plugin PLUMED.

(February 2013) Long-time scale MD code SISYPHUS is now available for download! SISYPHUS uses a combination of unbiased MD and biased Monte Carlo sampling. Read more about SISYPHUS in the original paper.
