Research Description

Our research group investigates Arctic radical chemistry through field measurements of trace gases and reactive radicals. We have developed and deployed spectroscopic instruments, including laser-based instruments using cavity ring-down spectroscopy and passive optical absorption instruments. Understanding of radical chemistry in the Arctic is critical for determining the fate of pollutants in the Arctic, including organics and mercury, and how this fate may change in a rapidly changing Arctic.
