I am a member of the Information Visualization department at AT&T Labs -- Research, working on network analysis, graph drawing, machine learning and general numerical algorithms. 










From 2001 to 2007, I worked at  Wolfram Research, developing numerical and graph theoritical software. Prior to April 2001, I worked in the 

Computational Science and Engineering Department

at 
Daresbury Laboratory, conducting research in algorithms for high performance computing.
