EDUCATION:

Ph.D. 2004, Cornell University

RESEARCH:

I will join Columbia University in Jan 2009 as an Assistant Professor. I received a Ph.D. in Physics from Cornell University in 2004 and did postdoctoral work at Princeton University. I do experiments in condensed matter physics.

Research in solid-state physics and chemistry is driven by the advancing complexity of new material systems. Some of these systems are nanoscale devices created using lithographic tools; others are complex materials created by advances in chemical synthesis. My research will focus on spectroscopic measurements of charge and spin transport at the nanoscale in such novel materials. The tools we will use are scanning probe microscopes to get atomic-scale spectroscopic information about the surfaces of materials and lithographic techniques to fabricate novel low-dimensional electronic devices.
