Current Projects at the CPS
Research in the Center for Photochemical Sciences focuses on a wide range of investigations into the role of light in chemical and physical processes. Such an emphasis enables collaborative, interdisciplinary research. Collaboration occurs between Center research groups, the Department of Biological Sciences and the Department of Physics and Astronomy. Collaboration also extends far beyond the University to national laboratories and other university research groups. This research focus encourages a strong academic/industrial interface and collaborative research between Center groups and major industries.
