Woz and I: with Steve Wozniak, co-founder of Apple and personal computer pioneer

 

I have been a member of academic staff at the University of Warwick for over eight years. I am affiliated with the Warwick Institute for Financial Computing and the Centre for Discrete Mathematics and its Applications (DIMAP). I belong to two research groups: Algorithms and Computational Complexity, and Formal Methods.

I received my Ph.D. from Imperial College (University of London) where I was also a postdoctoral researcher. Previously I was employed by the University of Calgary, Canada, and ATC-NY, USA. I have an M.S. from the University of Delaware and a B.Tech. from IIT Madras, India.

Teaching

In Spring 2001, I taught the third-year undergraduate course CS329 on parallel algorithms. Since the Autumn of 2002, I have been the course organiser for third and fourth year courses CS321 and CS406. The former is intended to give students insights into the IT industry through invited speakers. The latter introduces various research topics of current interest in computer science. Last year I taught CS406 and a new module, CS203, which is core for second year students and these are the modules I will teach this year.
