I'm a computational geometer/topologist with a growing interest in combinatorial optimization. I'm the senior member of the CS department's algorithms and theory group. I teach mostly large algorithms classes; you might find my lecture notes useful. Exactly half of my former PhD students have tenure. Among other administrative roles, I am an associate head of the computer science department, the chair of my department's faculty recruiting committee, the chair of the Computational Geometry Steering Committee, and a member of the SIGACT Committee for the Advancement of Theoretical Computer Science. I have too many hats. I have the lowest undergraduate GPA (2.4/4.0) of any professor I've ever met, although some of my colleagues came close, and some others never finished college at all. (I really shouldn't be proud of that.) I like pancakes.


It must be possible to replace in all geometric statements the words point, line, plane by table, chair, beer mug.

I believe in the third dimension, but not the other two.
