Okumura Group Homepage

The research activities of the Okumura group are in the areas of laser spectroscopy, kinetics, and reaction dynamics, applied to problems in atmospheric chemistry. We study atmospheric free radicals and transient intermediates in order to understand the reactions and photochemistry that are most important in the troposphere and stratosphere. Our goal is both to determine parameters of key reactions and species in the atmosphere, and to understand the chemical physics of these processes at the most fundamental level. Our work is performed in the Linde-Robinson and Noyes laboratories, featured in the images above!

Interested in our science?

The Okumura group frequently collaborates with young scientists and educators through programs like SURF and WAVE as well as informal summer mentorship. We believe that passion and diversity of thought and experience produces the best science, so if you are interested please contact us!
