JoAnn Williams is a member of the Center for Bioenergy and Photosynthesis and has developed the bacterial reaction center as an experimental system for probing the requirements for oxidation reactions.

Assistant professor in the School of Molecular Sciences. His research group’s primary focus is the structural biology of the membrane complexes involved in oxygenic photosynthesis.

Within AzCATI, Weiss researches the engineering of large-scale algae consortia for carbon capture and sustainable bioproduction. As ERM faculty, he educates on toxicological management and water treatment technologies.
