CV/Resume
Graph Theory/CS Blog: The Graph Enthusiast

I received my B.A. in Economics (minor in Mathematics) and M.S. in Computer Science from the University of New Mexico. I am currently
in my 2nd year of the University of Arizona's Computer Science PhD program. My advisor is Dr. Kobus Barnard. My research interests include
graph theory, graph drawing, combinatorial optimization, computer vision algorithms and image processing.

Research Projects

Stereo Gaze

This project deals with the development and testing of a Bayesian model for temporal scene inference. Given a video of a scene with people and objects the goal is to infer people's locations, their head pose, and also the locations of interesting objects in the scene.

Bipartite Graph Drawing

My previous research has dealt with various bipartite graph drawing problems. In the most traditional case the goal is to position the nodes of the bipartition on parallel layers in such a way that the total number of edge crossings is minimized. Problems that I've explored also include weighted and so-called bottleneck variants of bipartite crossing minimizationl.
