Arnab Bhattacharyya is a Ph.D. student at MIT, advised by Ronitt Rubinfeld. His research interests are algorithms (sublinear-time and otherwise) and extremal and additive combinatorics. He enjoys pigeonholing (his colleagues') arguments, chopping misbehaving objects into more well-behaved ones, and studying ZFC for surprise quizzes. Lately, he has been really yearning for the days when Federer was the dominant tennis player in the world.

Victor Chen did his undergraduate work at the University of Texas at Austin, and he obtained his Ph.D. under the supervision of Madhu Sudan at MIT. His research interests include property testing and combinatorics. In his spare time, he enjoys scavenging for used CDs and watching foreign movies.

Madhu Sudan received his Ph.D. from the University of California at Berkeley in 1992. From 1992 to 1997 he was a research staff member at IBM's Thomas J. Watson Research Center. From 1997-2009 he was a faculty member at the Electrical Engineering and Computer Science Department at the Massachusetts Institute of Technology. He is currently a Principal Researcher at Microsoft Research New England. His research has focussed on Probabilistic Checking of Proofs, List-Decoding, Property Testing, and Semantic Communication.
