Physical Chemistry

I am interested in the field of cold chemistry. Cold environments – typically temperatures less than 1 Kelvin under our experimental conditions – allow us to control the way in which reactions occur, providing information about fundamental reaction processes and underlying potential surfaces. Much of this detail is lost at higher temperatures, where thermal averaging complicates our interpretation of the dynamics at play. In the past few decades, extraordinary progress has been made in the development of techniques to form and trap cold species. In collaboration with the Softley research group, we employ a number of these techniques (described below) to investigate ion-neutral reactive collisions with unprecedented control and precision.
