My academic interests have varied with time: Electrical engineering (undergraduate), particle physics (PhD, postodoc and early years at Yale ) and condensed matter theory, since 1986. I am especially fond of field theory methods and the renormalization group.
I love my time in the class room. Of late I have been teaching undergraduates at the introductory and upper levels. I also spend some lecturing to the nonexperts: high school kids, Yale community, and the general public.
I spend my spare time reading novels and watching Seinfeld reruns. I am also trying perfect a way to do my taxes without using imaginary numbers.
