Research Program

Steve is working on deep-sea gelatinous zooplankton. He is doing research on bioluminescence, biodiversity, and ecology of deep-sea and open-ocean ctenophores, siphonophores, radiolarians, and medusae. In addition to assembling phylogenies for these groups, he is interested in cloning novel photoproteins and fluorescent proteins from these jellies.

Steve’s educational background includes a B.S. from Harvey Mudd College and a Ph.D. from the University of California, Santa Barbara.

He also holds an adjunct professorship in the Ecology and Evolutionary Biology department at the University of California, Santa Cruz.
