Accomplishments

Aurigene Discovery Technologies Ltd., Bangalore, India

(Oct. 2003 - present)

Continuously applied various computational chemistry and chemo-informatics techniques like Ab initio, Semiempirical, MD/MC (Molecular Dynamics and Monte Carlo) simulations, QSAR, CoMFA modeling, pharmacophore modeling, database search/screening, database building, homology modeling, and diversity analysis using various software applications like NWChem, MOPAC, MOE, SYBYL, GROMACS, Catalyst, and DVS-Solutions. I effectively interact with medicinal chemists, aiding them or seeking valuable inputs to design better compounds having therapeutic value.

Worked in close collaboration with synthetic chemists, biologists, X-ray crystallographers and NMR scientists to design focused library of small compounds for various protein targets in the class of proteases and kinases. ADME-property screening, Protein Ligand Docking (FlexX), Diversity analysis and Cluster analysis were employed intensively for designing focused library of small molecules. It was gratifying to note that many of my focused library yielded good leads, which we are presently optimizing. Close interaction with other members of multidisciplinary 'structure guided drug discovery' group gave me good idea about lead optimization techniques.

Designed and maintained database of diverse set of small molecular scaffolds. Applied various computational techniques to tackle problems related to drug discovery. Gained in depth experience with ligand based and receptor based pharmacophore generation and screening. Taught basic molecular modeling techniques to medicinal chemists. Did system administration of UNIX workstations. Installed and maintained various softwares for the computational chemistry group.

Used Python for writing compter programs for our routine tasks and also for adding modules, plugins for software package PyMOL.



University of Michigan, Ann Arbor, MI, USA

Department: College of Pharmacy

(Dec. 2001 - Sept. 2003)

Research focused on improving procedures for creating receptor-based pharmacophore models using the protein Folylpolyglutamate synthetase (FPGS). Study aimed in understanding the structure, function and ligand recognition of FPGS. Gained in-depth experience with Molecular Operating Environment (MOE) and SVL commands for working with proteins for ligand docking, homology modeling, sequence alignment and other techniques which assist in small molecular inhibitor design. Also, got exposed to developing force field parameters and for performing Molecular Dynamics simulation for understanding dynamics of protein structures using AMBER suite of programs. Developed force field parameters for the ligand Folate for the MD simulation with the protein FPGS and ATP.



Max-Planck-Institute, Mülheim an der Ruhr, NRW, Germany
