His research program explores the use of nanostructured material architectures for solar energy conversion. From 1996 to 2006, he was a research staff member at the IBM Thomas J. Watson Research Center in Yorktown Heights, New York investigating using polymer self-assembly for fabrication of high-performance semiconductor electronics. During his career, he has also performed experimental research in low-temperature scanning tunneling microscopy, single-electron tunneling devices, superconductivity in metal nanoparticles, nanocrystal-based electronic devices, and ferroelectric non-volatile memories. He earned his doctorate in physics from Harvard University and bachelor’s in physics and mathematics from Vanderbilt University. He is a fellow of the American Physical Society, a member of the Board of Directors of the Materials Research Society, and a senior member of the Institute of Electrical and Electronics Engineers.
