Grid Computing & Dependability
Cloud computing
Scalability
Data management
Cross-cloud applications
Datacenter design and efficiency
I also find Operating Systems and Virtualization immensly interesting topics
I started out in Grid computing working on automating management and configuration of Globus-based grids. Then the Cloud phenomenon began and I've since been examining cloud performance for scientific computing and most recently on developing cross-cloud abstractions to enable applications to be cloud-agnostic and therefore minimize lock-in.

B.A. in Computer Science and Mathematics from Hendrix College in 2004.
Master of Computer Science (MCS) from the University of Virginia in 2007
Summer 2008 - Microsoft Research Cloud Futures Group
I was
honored to be part of this group as it was just forming. I got to work
with incredibly talented people like Dan Reed, Savas Parastatidis, James
Hamilton, Jim Larus, and very briefly Dennis Gannon.
CS101 - Fall 2005
I'm originally from a small town in northwest Arkansas in the US. I enjoy most outdoor activites though I don't get around to them as often as I should given Charlottesville's fantastic location for outdoor recreation. I'm particulalry into running, paddling (whitewater generally), rock climbing, cycling, and the shooting sports.
I've been a competitive runner since high school but I've just recently started running marathons. My first marathon was the 2008 Charlottesville Marathon which I finished in 3:02 qualifying for the Boston Marathon which I was able to run in 2009. My goal was to beat Lance Armstrong's Boston time (2:50:58). The weather was good except for a persistent wind at the end of the race and I was able to finish in 2:47:28--mission accomplished! My next marathon will probably be the New York marathon. After that, who knows. Maybe some triathlons?
