Education:

August 2006-present:  Postdoctoral Research Associate, University of Colorado, Boulder,  CO, Advisor:  W. Carl Lineberger.
2001-2006:  Doctor of Philosophy in Chemistry, Washington University, Saint Louis,  MO.  Advisor:  Richard A. Loomis.
1997-2001:  Bachelor of Science in Chemistry, Wheaton College, Wheaton, IL.  Advisor:  Derek A. Chignell.

Career Interests:

Following completion of my postdoctoral studies, I desire to remain in academics at a college or university that emphasizes teaching at the undergraduate level.  There I hope to equip the students of today with the education necessary to make a difference in the world tomorrow.  

Research Interests:

Physical chemistry, including chemical reaction dynamics, chemical kinetics, molecular spectroscopy, and quantum mechanical effects.  Specific research interests include the stabilization of weakly-bound clusters using supersonic expansion techniques and subsequent characterization via frequency- and time-resolved laser spectroscopy, coupled with photoion/photoelectron imaging techniques. 

Awards:

Magna Cum Laude, Wheaton College (2001).
American Institute of Chemists Foundation Student Award Certificate for “outstanding student majoring in chemistry”, Wheaton College (2001)Freshman Chemistry Achievement Award, Wheaton College (1998).
