Professional Experience
1997 ÐSenior Research and Development Staff (2002-)
Research and Development Staff (1997-2001)
Research Professor (1996-1997)
Post Doctoral Scholar (1993-1996)
Oak Ridge National Laboratory, Oak Ridge, TN 37831-6096
Responsibilities include basic and applied research in welding metallurgy, phase transformations in steel, aluminum alloys, and nickel-base superalloys. For the first time successfully tracked the nonequilibrium phase formation during rapid weld cooling conditions using in-situ synchrotron diffraction. Modeled the inclusion formation in welds that has remained as an intractable problem before. Developed and executed wide range of applied projects related to welding consumable development, thermodynamics of alloy corrosion, high-temperature corrosion and advance welding process.
1992- 1993 Research Associate
Institute for Materials Research, Tohoku University, Sendai, Japan
Research into nanostructured magnetic materials, aluminum alloys and understanding fundamental phase transformations in steels using atom probe field ion microscopy. The research led to first experimental proof for the growth of paraequilibrium cementite during martensite tempering.
Education
1988 - 1992 Ph.D. (Materials Science)
University of Cambridge, Cambridge, UK
With physical metallurgy principles, innovative experiments, and computational models a complex microstructural transition that was observed in Fe-Cr-C welds was explained. The research paper based on these results was awarded with a prestigious Pfeil medal.
1986 - 1988 Master of technology (Industrial
Metallurgy - Welding)
Indian Institute of Technology, Madras, INDIA
By rapidly cooling the weld metal with Cu-backing, the weld microstructure and properties of Al-Zn-Mb alloys were improved. Graduated with distinction and Sudarshan Bhat Memorial Award
1982 - 1986 Bachelor of Engineering (Metallurgy)
P. S. G. College of Technology, Coimbatore, INDIA
Designed and fabricated a cold-chamber low-pressure die casting unit for ZincÐbase alloys as an undergraduate thesis project. The thesis was recognized with best project award from Director of Technical Education, Madras, INDIA. Graduated with distinction.
