My research interest covers three highly interdisciplinary fields of chemistry: bioinorganic structure and reactivity, computational method development, and physical organometallic chemistry and catalysis. A key aspect of my research philosophy is the close correlation of experiment and theory. I use spectroscopic techniques (mainly near-edge X-ray absorption spectroscopy (XAS) and Extended X-ray Absorption Fine Structure (EXAFS) to directly probe electronic and geometric structures of inorganic and bioinorganic systems. These XAS measurements are carried out at the beamlines of Stanford Synchrotron Radiation Laboratory, Menlo Park, CA and Advanced Light Source, Berkeley, CA. In addition, I employ a broad range of computational chemical methods, including forcefields, semi-empirical Hamiltonians, ab initio molecular orbital and density functional calculations to support and interpret experimental findings.
