Welcome to the Vaida Group research webpage. Our laboratory is located on the main campus of the Unversity of Colorado at Boulder in the Ekeley Sciences Building. We focus on physical chemistry research aimed at understanding atmopheric photochemical processes on Earth and Venus. Additionally we do work looking at the air water interface and the unique environment it provides for chemistry both in atmospheric problems as well as in plausible prebiotic chemical systems relevant to the emergence of life. Our work is done in the Department of Chemistry and Biochemistry as well as the Cooperative Institute for Research in Environmental Sciences (CIRES).
