Principal Investigator

By training I am a marine ecologist, with specific interests in the study of kelp forest and coral reef ecosystems. My research focuses on the ecology of coastal marine organisms, their role in nearshore ecosystems, and the response of these ecosystems to environmental change and human impacts.

Project Scientists

After graduating from UC Santa Barbara in 2008 with a B.S. in aquatic biology, Peter worked as a subtidal research technician within the network of marine protected areas surrounding the Santa Barbara Channel Islands. 

Katie is interested in the ecology of kelp forest and coral reefs, specifically how these habitats are structured by herbivory and how direct and indirect interactions with humans modify the processes of herbivory in these systems.

Avrey has bachelor and masters degrees from UC Santa Barbara in Aquatic Ecology. He currently manages subtidal and intertidal field operations.

Graduate Students

Ana is joined the lab in 2016 and is interested in researching animal aggregations. Click for more.

Technical Staff

Chris serves as our undergraduate lab manager.  He coordinates all the volunteers and organizes the vast number of samples that pass through the lab.


Darcy Bradley is a PhD candidate at the Bren School of Environmental Science & Management undertaking a research program that seeks to improve the management of coral reef associated top predators.

Ryan joined the Caselle Lab in 2016 and will be working on synthesizing long term data sets around the Channel Islands National Marine Sanctuary. 

Lauren worked as part of our subtidal monitoring program, conducting dive surveys in the rocky reefs in the Santa Barbara Channel. She is now a graduate student at Cal State Monterey Bay.

As an ecologist, April is interested in human impacts to predator-prey dynamics in marine systems. 

Sara primarily works on projects involving remotely deployed underwater video as a survey technique. She also works as a member of the subtidal monitoring dive team.

Brittany is a third-year undergrad and aquatic biology major at UCSB. While diving for PISCO last summer, she discovered the joy of waking up early on the ocean, especially if there’s coffee.
