I am aiming to complete my PhD by June 2008, and I'm currently looking
for postdoc positions and full-time positions in research laboratories
in machine learning / statistical signal processing. CV is available
upon request.
Research interests
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.
