Welcome

 

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.

Group reunion at the W. Carl Lineberger Memorial Symposium in Boulder

July 2, 2025
It was great for the current group to gather with Alums Profs. Caroline Dessent (University of York), Nathan Hammer (Ole Miss), Paul Campagnola (University of Wisconsin), and...

Congratulations to Abhi, whose talk at the Ninth Annual Student Research Symposium, hosted by the Local ACS Section was awarded second place!
