I lead the UT Systems and Storage Lab. I am broadly interested in systems-ish stuff: operating systems and distributed systems. Most of the work I've done so far has been in file systems, distributed systems, and storage. Recent interests: non-volatile memory, key-value stores, and verification.

I am interested in recruiting new students. If you are interested in working with me, please check out my page for prospective students and send me an email (after reading this!). Make sure to apply to the PhD program by the deadline (December 15).

If you are a student considering grad school or applying for grad school, these links may be useful (advice on contacting profs, getting letters of recommendation, etc.)

My research is supported by VMware and Facebook. I am an (consulting) Affiliate Researcher at VMware Research.
