My interests are in laser and Fourier transform spectroscopy of transient molecules, in atmospheric remote sensing and in molecular astronomy. High resolution spectroscopy is used to study high temperature species such as BeH2 and HBS in the infrared and free radicals such as CaCH3 and BaOH in the visible region. I am mission scientist of the Atmospheric Chemistry Experiment satellite (ACE, http://www.ace.uwaterloo.ca), which records infrared spectra of the Earth's atmosphere. The primary ACE science goal is the study of stratospheric ozone chemistry, but we are also looking at greenhouse gases relevant to climate change and at organics responsible for air pollution. My researchgroup also analyzes the spectra of "cool" astronomical objects including the Sun, brown dwarfs and extrasolar planets based on new laboratory measurements
