Research Interests:

Interdisciplinary materials studies, employing x-ray spectroscopy techniques to investigate the electronic structure of solids, both within the bulk and the near-interface region. I have taken the lead role in various experimental studies of organic compounds, correlated oxides, rare-earth nitrides, transparent conducting oxides, nitride semiconductors, and solid oxide fuel cell cathodes. Along with these projects, I directly supervise the graduate students in their research, upkeep the major multi-technique spectroscopy system at X1B, and assist various international research groups (e.g. Oxford University, Case Western Reserve University, Trinity College Dublin, Victoria University of Wellington, Jefferson Laboratory). I have extensive experience of ultra-high vacuum (UHV) equipment, and am considered an expert in the application of various spectroscopies, such as: soft x-ray absorption, x-ray emission, (and angular) photoemission spectroscopy; resonant inelastic x-ray scattering (RIXS).

I joined the Novel Materials Group of Prof. Kevin Smith at Boston University as senior post-doctoral research associate in August 2006. In September 2010, I became a Research Assistant Professor. I am also the beamline contact scientist for the undulator beamline X1B at the National Synchrotron Light Source (NSLS), Brookhaven National Labs (BNL) USA. I also perform experiments at the undulator beamlines 7 (soft x-ray fluorescence) 12 (angle-resolved photoemission) at the Advanced Light Source.

I am now an Assistant Professor at Binghamton University, State University of New York
