Curriculum vitae and Publications

I have been working mainly in condensed matter physics for the last several years, although my PhD and early career was in the field of high energy particle physics.
In the last few years, my research work has mainly been in the field of mesoscopic physics. More generally, I am interested in problems in field theory and in the application of field theoretic ideas to problems in condensed matter physics.
