I completed my PhD in June 2008. CV is available upon request.
My research lies in the intersection (or union) of statistical signal
processing and machine learning fields. For my MS research I have been
working on sparse signal representation theory and its applications to
source localization with sensor arrays. For my PhD I have moved to the
area of approximate inference in graphical models, with an emphasis on
Gaussian Markov Random Fields.
