PEOPLE

Jeremy T Claisse CPP Cal Poly Pomona Fish Biology Research

Jeremy is a quantitative marine ecologist with broad research interests mostly focusing on the life history and ecology of marine organisms associated with reef ecosystems, including California rocky reefs and kelp forests, coral reefs in Hawaii, and anthropogenic reef habitats (e.g., artificial reefs, breakwaters, submerged structures of oil platforms and renewable energy developments). Most of his work has an applied focus with an emphasis on habitat value assessment, marine conservation, fisheries ecology and marine habitat restoration. As a Professor at Cal Poly Pomona he teaches R coding, biostatistics, fish and marine ecology field courses.

Jeremy received his B.S. from UC Santa Barbara, and his Ph.D. from University of Hawaii Manoa where he was part of the Hawaii Cooperative Fishery Research Unit (USGS) and studied the life history and ecology of Yellow Tang with applications to managing its commercial aquarium fishery using marine protected areas. He did a postdoc at Occidental College with the Vantuna Research Group with whom he continues to collaborate extensively as the Associate Director, working on a variety of applied marine ecology projects across the Southern California Bight.

Casey's thesis project focuses on relationships among planktivore (Chromis punctipinnis) and predator (Paralabrax clathratus) densities and the habitat characteristics of southern California artificial reefs. He is working on our CSU COAST SSINP project, processing sonar data to quantify artificial reef habitat characteristics and developing an ESRI ArcGIS StoryMap as an outreach product. He also was a 2025 NSF IRES-CR international research experience intern in northwest Costa Rica, doing shark and ray capture and tagging, coral restoration and surveys, and cetacean surveys and acoustics analysis. He started in our lab as an undergrad, processing fish to examine the effect of Palos Verdes MPAs on fish age structure and got a CSU COAST undergraduate research award to conduct a related literature review and presented it as a poster at the CPP's Annual Science Research Symposium. He also worked at Cal Poly Pomona's Rain Bird Biotrek, maintaining the the ethnobotanical garden and giving tours to K-12 groups. Casey has completed both his PADI Open Water and Advanced SCUBA certifications through the CPP BRIC SCUBA Program, and then got his AAUS Scientific Diver Certification and MOTC boat operator certification through SCMI. He also participated in CPP’s Ernest Prete Jr. Fellowship Program as an undergrad, tutoring and teaching biology lessons at Kellogg Polytechnic Elementary School, and was rehired as a grad student to be a Prete mentor, helping undergrad Prete fellows develop their biology lessons.

Natalie Shubin

Natalie is developing her thesis project on using fish reproductive output densities to quantify the effects of southern California MPAs and artificial reef habitat characteristics. Before joining the masters program, she was worked in the lab as a research assistant for the CSU COAST SSINP projects, writing R code to quantify habitat characteristics from sonar data layers using the MultiscaleDTM R package. She is now currently developing a shiny application and quarto report to visualize results from the lab's artificial reef projects. She began working in the lab as a CPP undergrad processing fishes, removing and weighing otoliths and gonads, for a larger lab project investigating the effects of the Palos Verdes MPAs on fish age structure. She also successfully wrote a proposal for and was awarded a  CSU COAST undergraduate research award for this project. Natalie also works as a Scientific Aid for California Department of Fish and Wildlife as a sampler for the California Recreational Fishing Surveys (CRFS) in Orange County where she enjoys connecting with anglers and refining her fish ID skills. Natalie has also collaborated on the California Marine Report Card Project at the Aquarium of the Pacific. She wrote about her experiences in the Aquarium’s Pacific Currents column, Fresh Voices. She is also a biostatistics lab TA, teaching students foundational concepts of statistics and R coding. Natalie also received her PADI Open Water and Advanced SCUBA certifications through the CPP BRIC SCUBA Program.

Chelsea_Williams_Garibaldi_Photo_J_Clais

Chelsea's master's thesis research focused on spatial variation in the life history of the Garibaldi (Hypsypops rubicundus), a damselfish native to kelp forest ecosystems in southern California and Baja California, Mexico (LINK TO PUBLICATIONS HERE & HERE). She found they grow larger on breakwater than natural reefs, grow larger and live longer in cooler locations in southern California, and subsequent work found these patterns were associated with diet differences. She was also able to validate the annual periodicity of otolith increment formation and discovered they can live at least 57 years! Chelsea currently works as the Assistant Director of the Vantuna Research Group at Occidental College.
