Colin is a fisheries biologist with nearly 15 years of experience researching fish and invertebrates in marine, estuarine, and riverine ecosystems. He specializes in taxonomy, focusing on larval fish, zooplankton, mysid shrimp, and amphipod taxonomy. Colin trained under Dr. Johnson C.S. Wang, noted ichthyologist, regarding the identification of Sacramento-San Joaquin Delta larval fishes. In this role, Colin manages the lab in Richmond, California. His work examines factors that affect Delta Smelt, Longfin Smelt, and juvenile Chinook salmon in the upper San Francisco Estuary.

Colin has identified and enumerated larval fish, amphipod, mysid, and zooplankton from samples collected in the Sacramento-San Joaquin Delta for Contra Costa Water District, California Department of Water Resources, University of California, Davis, ICF International, and the Delta power plants. He has experience identifying larval fish species of the Sacramento-San Joaquin Delta, with an emphasis on larval delta smelt, longfin smelt, and wagasaki.
