I am a second year PhD student in the Computer Science Deparment at Carnegie Mellon University. I'm co-advised by Greg Ganger and Nathan Beckmann. I'm part of CORGi @ CMU and the Parallel Data Lab.

Generally, I am interested in computer systems, particularly distributed, caching, and storage systems. Currently, I am researching how to cost-effectively cache billions of tiny objects in flash.

I recieved my undergraduate degree at Harvey Mudd College in computer science, where I recieved the Class of '94 Award for excellence in research, course work, and service. During my undergrad, I worked on modelling I/O for data structure design with Don Porter at UNC Chapel Hill and the BetrFS group.
