I am a Professor of Computer Science at Harvard. My research is in the theories of computation and communication. I am very interested in understanding the many ways in which communication or computation can go wrong (i.e., have errors), and how to correct all such errors.
My Bulletin Board:
• I will be on sabbatical in Fall 2025. You can still reach me by email though responses may be delayed if I am travelling.
