Anant Sahai is an American electrical engineer and computer scientist who holds the Qualcomm Chair in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley.[1][2] His research areas include information theory, control theory, machine learning, and wireless communication.[3]
Early life and education
Sahai grew up in Thousand Oaks, California. His father, Rajeshwar, was an electrical engineer at Rockwell Research Center, and his mother, Jyoti, was a laboratory technician.[4] As a senior at Thousand Oaks High School, Sahai was the highest individual scorer in the 1990 California Academic Decathlon, earning 8,878 of a possible 10,000 points. He won gold medals in mathematics, science, fine arts, and best overall score.[4]
Sahai received his B.S. in Electrical Engineering and Computer Sciences from UC Berkeley in 1994.[1] He then attended the Massachusetts Institute of Technology, where he earned his S.M. in 1996 and his Ph.D. in 2001, both in Electrical Engineering and Computer Science, under the supervision of Sanjoy Mitter in the Laboratory for Information and Decision Systems.[1][5] His doctoral dissertation, Anytime Information Theory, addressed connections between control and information theory.[5]
Career
After completing his Ph.D., Sahai worked at the startup Enuvis, Inc. in 2001, developing adaptive software radio techniques for GPS detection in low signal-to-noise ratio environments.[1] He joined the UC Berkeley faculty in 2002.[1] Additionally, he served as Treasurer of the IEEE Information Theory Society from 2007 to 2009.[6]
Research
With Mitter, Sahai developed the concept of anytime capacity and showed that it characterizes the ability to stabilize unstable linear systems over noisy communication links.[7]
Sahai's group has studied fundamental limits of spectrum sensing for cognitive radios, including cooperative sensing and "SNR walls", which are thresholds below which detection becomes impossible regardless of observation time.[8][9]
His work with Pulkit Grover and Kristen Woyach on system-level power consumption from an information-theoretic perspective won the 2012 IEEE Communications Society Leonard G. Abraham Prize.[10][11]
Personal life
Sahai's brother is Amit Sahai, a professor of computer science at UCLA.[4]
