Major professional interests include : experimental low temperature condensed matter physics; nanolithography; properties of metallic, semiconducting and insulating mesoscopic systems at millikelvin temperatures; magnetic and transport properties of metals with dilute magnetic impurities, transport at superconducting/normal-metal interfaces, persistence currents in normal metals, quantum interference phenomena in disordered metals, single electron charging phenomena in insulators and semiconductors; transport and magnetic properties of small ferromagnetic particles. Education : Ph.D. in Applied Physics (1989) Yale University, M.S. (1985) Yale University, and B.S. (1983) Muhlenberg College, Allentown, PA. Recognitions : National Science Foundation Young Investigator (1993-98), Alfred P. Sloan Fellow (1994-1996), and David and Lucile Packard Foundation Fellow (1995-2000). Assistant Professor, Department of Physics and Astronomy, Northwestern University (1992-1999), Associate Professor, Department of Physics and Astronomy, Northwestern University (1999-Present). Chair of the Department of Physics and Astronomy at Northwestern University since September 1, 2007.
