EDUCATION:

Ph.D. 2004, Cornell University

RESEARCH:

I joined Columbia University in January 2009 as an assistant professor. My area of research is experimental condensed matter physics. I use scanned probe microscopes (scanning tunneling and atomic force) to get atomic-resolution structural and electronic information on quantum materials. We do a significant amount of microscope building and design, and collaborate with scientists both at Columbia and outside to obtain samples that are of interest. Current projects include studies of charge density wave materials, heavy fermions and graphene.
