Research interests:

Biomolecules and their assemblies are complex chemical systems. Understanding their mechanisms of functions require various methods of investigations, in truly interdisciplinary mode, covering theoretical, experimental, computational methods and even data analytics. In our group we address those questions on the mechanism of functions Biomolecular systems, which would require insights not only from the molecular structures but also would need the information on the dynamics of the constituent atoms; in fact in real systems the atoms and molecules in a cell are always jiggling, dancing and bumping into each other at any given temperature. For example, one may figure out a model structure of a protein from the experimental measurement or may obtain from from a structure database, but that may not be sufficient to guess the mechanical flexibility of the system which could have relation with the function. The dynamics could be simulated in computer using fundamental principles of Chemistry, Biochemistry, Physics and the obtained datasets are analyzed using statistical methods to interpret the observations in Life sciences. The computations are done on large scale parallel computing platforms, often using GP-GPU based machines.

Our systems of interests are proteins, lipids, nucleic acids, small molecule (drugs). These exercises only tells us how do the biomolecules function but also lead to understand the kind of errors at the molecular level that can result functional defect and diseases. Once this is understood, it provides a direction for designing a lead compound (drug molecule) in a rational manner. Some of our recent interests include (i) mechanism of conformational modulations on αβ-Tubulin dimer and their control over cell divisions, (ii) structural dynamics of the Bcl2 family of proteins and their role in apoptosis and cancer therapy, (iii) Kinase allosteric and their inhibition using drug molecules, (iv) ligand design and various others.

Primarily we use standard molecular dynamics methods to simulate the all-atom dynamics of the systems and also use more advanced methods of accelerated molecular dynamics to compute the free energy landscapes of the biomolecular functions.
