Research Summary

Using state-of-the-art tools of molecular modeling, computer simulations, and statistical mechanics, Professor Sarupria's research focuses on surface-driven phenomena. The central theme encompassing her research involves developing cutting-edge sampling techniques in molecular simulations and applying them in understanding long-standing problems in condensed matter. Current projects include heterogeneous ice nucleation, protein adsorption on surfaces, and fouling on water purification membranes. She recently developed novel transition path sampling methods and software to enable their large-scale implementation in high-performance computing infrastructures. These methods will be used to study ice nucleation, and reactions in condensed phases, including enzymatic reactions.

Research Page

Professor Sarupria received a master’s degree from Texas A & M University where her thesis focused on thermodynamic modeling of clathrate hydrates of gas mixtures formed in the presence of electrolyte solutions. She obtained her doctorate from Rensselaer Polytechnic Institute, where she studied pressure effects on water-mediated interactions and proteins. She was a post-doctoral researcher in Princeton University and studied hydrate and ice nucleation using advanced path sampling techniques.
