CS Theory Group

About us

Our research interests range over many areas of algorithms and complexity theory. These areas include parallel computation, computational geometry, data structures, graph algorithms, network algorithms, distributed computation, computational biology, information theory, analytic combinatorics, random structures, approximation algorithms, sublinear algorithms, error-correcting codes, cryptography, computational algebra. Much of the research reflects interaction with other areas, such as information security, databases, geographic information systems, bioinformatics and mathematics.
