Brief Biodata:

Following his Ph. D.. from the University of Texas at Austin in 1973, Prof. Ananthakrishna held post-doctoral positions at UT, Austin and at IISc, Bangalore. He then joined the Indira Gandhi Centre for Atomic Research at Kalpakkam in 1975. Since 1990 he has been a member of the faculty at MRC.

He has also been a visiting professor at University of Brussels, Brussels and University of Metz, France and a visiting Associate at the International Centre for Theoretical Physics, Trieste, Italy, 1989-93. He has served on the editorial board of Materials Science and Engineering from 1995 to 2004. He is a fellow of the Indian Academy of Sciences, the Indian National Science Academy and a fellow of the Asia Pacific Academy of Materials. He is a recipient of the Materials Research Society of India Medal for 1992 and Annual Superconductivity and Materials Science Award, MRSI , 2005.
