Biography

Anant did his undergraduate work in EECS at UC Berkeley from 1990-1994. From 1994-2000 he was a graduate student at MIT studying Electrical Engineering and Computer Science (Course 6 in MIT-speak) and was based in the Laboratory for Information and Decision Systems. In 2001 he was on the theoretical/algorithmic side of a team at the startup Enuvis, Inc. developing new adaptive software radio techniques for GPS in very low SNR environments (such as those encountered indoors in urban areas). He joined the Berkeley faculty in 2002.

He currently serves also as faculty adviser to UC Berkeley's chapter of Eta Kappa Nu and as the Treasurer for the IEEE Information Theory Society.
