Brian Thomas, assistant professor, physics and astronomy, has received $446,000 from the National Aeronautics and Space Administration, through the Astrobiology: Exobiology and Evolutionary Biology Program, for the project “Astrophysical Ionizing Photon Events and Primary Productivity of Earth's Oceans.” Funds will be used to study and substantially improve predictions of the impact of a wide range of astrophysical ionizing photon sources on primary producers in Earth's oceans. This project will be for three years and includes the University of Kansas and the Smithsonian Environmental Research Center as collaborators.
