Areas of Research and Expertise

The elucidation of how simple chemical change occurs.
The tools for studying chemical reaction dynamics have
encompassed shock tubes, gas phase radiolysis, infrared
chemiluminscence, molecular beams, and laser based
techniques. Currently, time- and frequency-resolved laser
absorption spectroscopies are being used to characterize
a variety of simple chemical reaction processes, from
determining product state distributions under single
collision conditions to the measurement of reaction rate
constants and branching ratios in radical-radical reactions.
