Qualifications Have been trained in X-ray crystallography, Electron Microscopy, Structural Biology, Virology and various aspects of Biochemistry and Molecular Biology.

Molecular Biology and Biochemistry
Experience in many aspects of Molecular Biology and Protein Chemistry including cloning/subcloning and insertion of genes into vectors, design and construction of synthetic genes and subsequent insertion into vectors, overexpression of foreign genes in E. coli. (including techniques to induce expression of soluble proteins), purification of soluble and insoluble proteins (including refolding) by batch methods, affinity-tagging, chromatography, electrophoresis etc., biophysical characterization with techniques like gel electrophoresis including native, IEF and SDS PAGE, CD spectroscopy, Dynamic Light Scattering, and chromatographic methods including gel filtration.

Crystallography and Electron Microscopy
Extensive training in protein crystallography with experience in most aspects of structure determination and structure analysis including crystallization, data collection and processing, structure determination by Molecular Replacement and MAD methods, model building and refinement etc. Have extensive experience and familiarity with standard program packages like CCP4, CNS/XPLOR, O, Solve, Sharp etc.

Have been involved in theoretical studies in certain areas of crystallography like Phase determination in MIR cases (Kumar and Rossmann, 1996, Acta. Cryst., D 52: 518-520) and data generation using NCS operators in sparse data situations (unpublished).

Have been involved in using Electron Microscopic information to generate initial low resolution phases 

Computation
Extensive computer skill in Unix environment including shell script,  awk, Perl and programming languages like FORTRAN and C. 

A few of the programs authored by me:
MASK_OVERLAP: A program to check/edit the existence of any possible overlaps in a mask arising from NCS and/or Crystal symmetry operators. 
DEALPDB: A general utility program to perform a series of operations on a set of pdb coordinates in an interactive or batch mode.
DEALMAP: A general utility program to perform a series of operations on a map file in an interactive or batch mode.
MATRIX: A general-purpose matrix manipulation program. 
A small package of 2D image manipulation programs for Electron Microscopic analysis.

A set of Web-based Perl programs for Molecular Biology applications.
