Ashwin Lall
Ashwin Lall joined the Denison faculty in 2010. Prior to this, he was a postdoctoral researcher at Georgia Tech, a Ph.D. student and Sproull fellow at the University of Rochester, and a math/computer science double major at Colgate University. Dr. Lall has taught all the existing flavors of the introductory Computer Science course as well as advanced topics such as Theory of Computation and Design/Analysis of Algorithms. He also enjoys teaching the Game Design elective in the CS major.
Research
My research focuses on the design and analysis of algorithms for very large data sets. I have worked in a number of subfields of Computer Science, including computer networks, databases, social networks, distributed computing, and natural language processing/artificial intelligence. I am interested in doing summer research with students on query optimization. Interested students should drop by my office to discuss possible projects.
