Our Research

The ocean controls the Earth’s climate and stores most of its heat and carbon. Our lab works to understand the processes controlling the exchange of carbon and heat between the ocean and atmosphere, and how these processes interact with anthropogenic climate change. Our work focusses on both physical processes, such as large-scale ocean circulation patterns, and biogeochemical processes, such as biologically-driven carbon uptake in the ocean.

Group Members

Prof. Tim DeVries

Prof. DeVries leads the Ocean Circulation and Biogeochemistry group at UCSB. His research focuses on numerical models of ocean circulation and biogeochemistry, ocean carbon and nutrient cycles, ocean circulation and climate variability, probabilistic models, and data assimilation models. Prof. DeVries has a PhD in Earth System Science from University of California, Irvine. He has been a faculty member at UCSB since 2014. CV here.

Aaron Bagnell

Aaron is a graduate student in the Interdepartmental Graduate Program in Marine Science at UCSB. His current research focuses on applying machine learning models to study variability in physical and biogeochemical data, and modeling this variability with ocean circulation and biogeochemistry models. Aaron has a BA in Geophysics from University of California, Berkeley. He has been a member of the DeVries lab since 2015.

Dr. Saeed Roshan


Saeed is a postdoctoral scholar in the Department of Geography at UCSB. His current research focusses on trace metal geochemistry, and modeling the biogeochemical cycles of trace metal species in the ocean. Saeed has a PhD in Marine Science from the Rosenstiel School of Marine and Atmospheric Science at University of Miami. He has been a member of the DeVries lab since 2016.
