I am an assistant professor of Computer Science at UC Santa Cruz, since 2015. Previously, I was a Principal Member of Technical Staff at Sandia National Labs, Livermore in the Information Security Sciences department. My work is primarily focussed on mathematical foundations of big data problems. I am interested in applying theoretical computer science methods (especially random sampling and sublinear algorithms) to real-world problems involving massive data sets.

Brief Bio

C. Seshadhri is an assistant 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, he works at the boundary of theoretical computer science and data mining. His work spans many areas: sublinear algorithms, graph algorithms, graph modeling, scalable computation, and data mining. His background is in theoretical computer science, specifically sublinear algorithms. He got his Ph.D from Princeton University and spent two years as a postdoc in IBM Almaden Labs.
