I am a 4th year Computer Science Ph.D. Candidate at Cornell University. My advisor is Prof. Ken Birman. My research focuses on distributed systems, and I am particularly interested in those that solve real problems and embody deep trade-offs. My work-flow has three stages. First I stumble on an interesting real-world problem (this is the tricky part). I gather traces and create mathematical models about the current or expected behavior that a system needs to satisfy. Finally, I design and implement a system to solve the problem that optimizes for these expected use cases.

I spent the summer of 2008 at Yahoo! Research, where I worked with Brian Cooper, Raghu Ramakrishnan and Adam Silberstein on Distributing Range Queries for Large-Scale Ordered Tables.

I received my B.Sc. in Mathematics from the University of Iceland in May 2005. My advisor was Prof. Magnus M. Halldorsson.
