Michael Walfish

I am an assistant professor in the Computer Science department at The University of Texas at Austin.

I was most recently (Autumn 2008) at University College London (UCL), in the networks research group in the Department of Computer Science, working for Brad Karp and with David Mazières. Before that (November 2007 to August 2008), I was a postdoc at Stanford with David Mazières, and before that (September 2002 to November 2007) a graduate student studying Computer Science in the Networks and Mobile Systems Group (NMS) in the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT. My advisor was Hari Balakrishnan.

Here is my dissertation.

Here is my CV.
