Research Focus

Development of methods in Computational Molecular Biology and their application to proteins of therapeutic interest to understand the structural basis of their function and signaling in normal and disease physiology with a focus on metabolic disorders, pancreatitis, and pancreatic cancer. Conformational view of G protein-coupled receptors' pleiotropic signaling. Translation of signaling hypotheses into rational therapeutic design.

Research Contributions

One of the leaders in de novo structure prediction of the multiple conformations of GPCRs; developed a novel and super-efficient conformational sampling algorithm for GPCR structure prediction; discovered several lead molecules for multiple protein targets with promising pre-clinical activity.

Current investigations include:

Method development for the prediction of active GPCR conformations with potentially biased coupling to G proteins, GRKs, and arrestins. Targeting gut GPCRs (including taste receptors among others) for diabetes. Probing the role of Ghrelin and its receptors in Cachexia during pancreatic cancer. Probing the role of PKD in pancreatitis for a rational design of therapeutics.
