Consider submitting your best work!

Welcome to my academic homepage! I am a member of the faculty in the department of Electrical and Computer Engineering at Carnegie Mellon University with a courtesy appointment in Computer Science, and a member of the Parallel Data Lab.

My research interests include, but are not limited to: scalable storage performance and reliability, operating and distributed systems, data analysis and modeling.

Want a quick overview of our most recent work? Check out this video and this article and this article and this article. The best way to learn more, however, is to click the buttons below and check out the relevant publications for each project.

Note to prospective Ph.D. students: There is no need to email me to tell me you plan to submit an application. If you want to make sure I won't miss your application then (a) apply through the ECE department, and (b) include my name in the list of faculty you are interested in working with. Best of luck!

Note to current M.Sc. students: If you want to try your hand at research, take a look at our ongoing projects. Like what you see? Then reach out with your CV and transcript!
