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.
