Brief Biodata:

Dr. Ravishankar obtained his B.Tech. degree in Metallurgical Engineering from ITBHU, Varanasi in 1991. He then continued in the same field and obtained his M. Sc. and Ph. D. degrees from IISc, Bangalore in 1993 and 1998 respectively. During his Ph. D. he spent time as a exchange program student at Toyohashi University of Technology, Japan in 1996. Following his Ph. D., he was a Post Doctoral Researcher and then Research Associate with Prof. Barry Carter's Research Group at the University of Minnesota from 1998 till 2002. Since 2002 he has been on the faculty of the Materials Research Centre.
