My main research interests lie in the area of experimental condensed matter physics. The primary goal is to understand the underlying physics of novel materials and nanostructures and how complexity gives rise to unusual and extreme properties. Specific research topics include: science and technology of carbon nanostructures such as graphene and nanodiamond, and the science of correlated materials as high temperature superconductors and colossal magneto-resistance manganites. We utilize novel state of the art experimental tools to uncover the electronic properties of materials with energy, momentum, spatial, spin and time resolution (angle resolved photoemission spectroscopy (ARPES), nano-ARPES, Spin-ARPES and laser ARPES). We are also developing novel way to synthesize two dimensional graphene and functionalized graphene for electronic and energy related applications.

Using ultrafast lasers, Berkeley Lab scientists have tackled the long-standing mystery of how Cooper pairs form in high-temperature superconductors. With pump and probe pulses spaced just trillionths of a second apart, the researchers used photoemission spectroscopy to map rapid changes in electronic states across the superconducting transition.
