Our Mission

The Britt lab is investigating structure and function of biologically significant enzymes with redox-active transition metal centers, clusters or organic radicals in their active site. The oxygen-evolving complex of Photosystem II, the enzyme complex responsible for water oxidation in photosynthesis, is the major biological system currently under investigation.

Our primary research tool is advanced Electron Paramagnetic Resonance (EPR) spectroscopy. We operate the CalEPR center , home to five continuous-wave and pulse EPR instruments ranging in frequency from 9 to 130 GHz. CalEPR is the largest center of its kind on the West coast.
