Michael Walfish

I recently graduated. Here is my dissertation.

Right now, I am a postdoc, working for "Professor" David Mazières in Stanford's Computer Science department. I used to be 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.

Beginning in January, 2009, I will be an assistant professor in the Computer Science department at the University of Texas at Austin. Once at Texas, I will be looking for strong students, so if you are interested in pursuing a PhD in Computer Science and are excited by networked and distributed systems, please get in touch any time.

Here is a (slightly-out-of-date) CV.
