Jim Johnson received his B.S. and M.S. in Chemistry from the Florida State University and holds a M.E. in Engineering from the University of Florida. Jim's thesis work centered on Photosystem II under the direction of Dr. P. H. Homann. Jim has recently joined our group to initiate and analyze next-generation sequencing projects (NGS) in an effot to further our understanding of avian carotenoid ornamentation. Jim has also introduced us to the biochemical mechanisms of carotenoid pigmenation.
