Cambridge Theory and Semantics Group - Centred around mathematical models of a variety of languages and logics, using techniques such as structural operational semantics, linear logic, domain theory and category theory. Strong links with Logic and Set Theory in the Pure Mathematics Department.
ICS Theory Group - University of California, Irvine. Research centers on the design and analysis of algorithms and data structures as well as computational complexity.
MIT LCS Theory of Computation Group - Research areas include algorithms, complexity theory, computation and biology, cryptography and information security, distributed systems, numerical analysis and scientific computing, semantics, and supercomputing technologies.
Oxford University Computing Laboratory - A centre for research in computer science, numerical analysis, computational biology, quantum computation, computational linguistics, and information systems.
The PORTIA Project - This project focuses on both the technical challenges of handling sensitive data and the policy and legal issues facing data subjects, data owners, and data users.
Stanford CS Theory - Research includes sequential and parallel algorithms, computational problems in databases, computational geometry, design and analysis of programs and programming languages, and combinatorial, logical, and algebraic mathematics.
