About Our Group:

We design, build and exploit new types of instruments that provide qualitatively new pictures of how chemical reactions occur. By coupling mass-selective vibrational spectroscopy with cryogenic ion processing, we are able to study a wide variety of chemical phenomena, including small molecule activation, gas-liquid interfacial chemistry, and intracluster hydrogen bonding.
