James Hannon received a PhD in Physics from the University of Pennsylvania in 1994, under the supervision of Ward Plummer.  His thesis work focused on the atomic structure and lattice dynamics of beryllium surfaces.  He then spent two years as a Humboldt Fellow with Harald Ibach at the Forschungszentrum Juelich where he studied alloying mechanisms with electron energy loss spectroscopy (EELS) and scanning tunneling microscopy (STM). In 1996 he moved to Sandia National Labs, working as a postdoc with Gary Kellogg on low energy electron microscopy (LEEM).  He performed real-time in situ measurements on silicon surfaces, investigating key processes such as boron segregation and oxygen etching.  In 1998 he joined the Physics Department at Carnegie Mellon University. In 2000 Hannon joined IBM's T.J. Watson Research Center, continuing research on surfaces using LEEM. His research activities at IBM are centered on surface phenomena, including strain-driven self-assembly, novel growth mechanisms, nanowire growth, and graphene synthesis. He now manages a research group focused on the purification and integration of carbon nanotubes for applications in high-performance logic.  He also manages the materials effort in earth-abundant photovoltaics.   He is the author of over 50 refereed publications, including articles in Science and Nature. He is a Fellow of the American Physical Society.
