Department of Energy. He received his Ph.D. from Rice University at 2005 with Jun Kono and joined Lawrence Berkeley National Laboratory as Postdoctoral under Daniel Chemla. He is working in experimental condensed matter physics, focusing on femtosecond laser spectroscopy and ultrafast transient phenomena in nanostructures and quantum materials. His current projects include ultrafast magnetism in strongly correlated electrons, ultrafast dynamics of iron pnictide superconductors, nonlinear optics in metamaterials, ultrabroadband electrodynamics in carbon nanotubes and graphenes. He is recipient of the NSF CAREER award and LAS Award for Early Achievement in Research at Iowa State University.
