Brief Bio
C. Seshadhri (Sesh) is a professor of Computer Science at the University of California, Santa Cruz. Prior to joining UCSC, he was a researcher at Sandia National
Labs, Livermore in the Information Security Sciences department, during 2010-2014. His primary interest is in mathematical foundations of big data,
especially modeling and algorithms. By and large, Sesh works at the boundary of theoretical computer science (TCS) and data mining.
His work spans many areas: sublinear algorithms, graph algorithms, graph modeling, scalable computation,
and data mining. In the theory world, his work has resolved numerous open problems in monotonicity testing and
graph property testing. A number of his papers in the interface of TCS and applied algorithms have received
paper awards at KDD, WWW, ICDM, SDM, and WSDM. He received the 2019 SDM/IBM Early Career Award for Excellence in
Data Analytics. Sesh got his Ph.D from Princeton University and spent two years as a postdoc in IBM Almaden Labs.
