Adv. Mater Cover
  • Research Assistant: (1/98–7/01) at the University of Illinois at Urbana-Champaign, Urbana, Ill. with Professor Andrew A. Gewirth
    Synthesized and characterized novel metal (Au, Ag, Pd, Pt) nanoparticles stabilized with inorganic oxoanions (molybdate, tungstate, chromate) for applications in catalysis. Particles were synthesized using a variety of chemical reduction methods and characterized with techniques including: electrochemistry, electron microscopy, and numerous spectroscopies (IR, UV-vis, X-ray photoelectron, energy dispersive X-ray, and Raman).


  • Undergraduate Research Assistant: (5/95–8/96) at St. Olaf College, Northfield, Minn. with Professors Mary M. Walczak and John P. Walters
    Studied derivatives of ferroin using UV-Visible spectroscopy and several electrochemical techniques. Developed software for integration of spectrometer with computer using LabVIEW. Developed experiments for instrumental analysis laboratory.
