I lead the UT Systems and Storage Lab. I am also a part of the LASR research group. 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: key-value stores, non-volatile memory, and verification.
I am interested in recruiting new PhD students. I am not currently hiring Masters 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.)
I maintain the SOSP/OSDI Hall of Fame and the FAST Hall of Fame. These pages indicate who has published the most at these premier venues, and who has been publishing recently. These are good guides for grad students trying to decide which professor to work with!CS 380D
