I am a fifth-year Ph.D. Candidate in Computer Science in the Aqualab under my advisor, Dr. Fabián Bustamante. I received a Master of Science degree in Computer Science from Northwestern University in 2011, and graduated cum laude with a Bachelor of Science degree in Computer Science from Northwestern University in 2007.

Here is my Curriculum Vitae.

Statement

My primary focus is on building and evaluating large-scale distributed systems, with a goal of understanding their interactions with and impact on the Internet at large.

I also am interested in approaches to attain urban sustainability, using vehicular-based sensing nodes to collect high-fidelity pollution measurements that can be used to inform urban policy decisions, and the general public.

Skiing and Snowboarding

It's been a few years since I've had a chance to get out on the slopes. I love skiing in the Vail area of Colorado, but when I can't be there, you'll find me at Cascade Mountain near the Wisconsin Dells.

Racquetball

I've been playing for a few years now, and I'm looking for others to play against. If you're interested, please let me know!

Photography

As an amateur photographer, I enjoy experimenting with new techniques to create unique effects. I shoot with a Canon EOS 350D Digital Rebel XT and (usually) a Sigma 15-30mm lens.

Check out my Flickr photostream!

Scuba Diving

I have logged a few days worth of dive time, predominantly in southern Florida and the Keys, and also in Negril, Jamaica.

Web Design

My website projects include:

• Commemorative Air Force: Wisconsin Wing
• Regina Music Box Center
