Experience
Pacific Northwest National Laboratory, Richland, Washington
Post Doctorate (2006 to Present). Studies of NOx storage/reduction systems with a variety of ultra-high
vacuum surface analysis techniques. Research focused on the physico-chemical
properties, electronic structures and surface reactions on Al2O3, BaO/Al2O3, Pt/Al2O3, and Pt/BaO/Al2O3 model catalysts. These model systems allow understanding the basic
processes on the atomic level.
Department of Chemistry, Texas A&M University, College Station, Texas
Post Doctorate and Research Assistant (2000-2006). Application of a variety of ultra-high vacuum
surface analysis technique to study model catalysts and important fundamental systems.
Techniques include temperature programmed desorption (TPD), low energy ion
scattering spectroscopy (LEISS), Auger electron spectroscopy (AES), low energy
electron diffraction (LEED), x-ray photo electron spectroscopy (XPS), and infrared
reflection absorption spectroscopy (IRAS). Research focused on the electronic structures
and adsorbate reactions on metal, metal-oxide, and metal on metal-oxide systems.
