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!

Remembering Mario Molina
10/13/2020

Remembering Mario Molina

In light of Mario Molina's death last week, we want to acknowledge his works' immeasurable impact on the environmental health of our planet. Mexican chemist Mario Molina was a co-recipient of the 1995 Nobel Prize for his work on Stratospheric chemistry. Most important was his contribution in identifying the threat of chlouroflourocarbons to our protective ozone layer. By identifying the key mechanisms responsible for ozone destruction, he laid the foundation for policymakers to make almost immediate action to protect our planet by reducing and eventually banning emission of many responsible chemicals. We honor him today by encouraging those reading to channel his passion and strength in fighting our current climate crisis, in anyway you can. Research, teach, share, and vote! We only have one earth. Thank you Dr. Molina
