Welcome to the Marine Environmental Change (MEC) Lab at the Claremont Colleges!

I run a student-centric research program with external funding from the NSF, NOAA, and NGS. In my research, we develop and interpret records of environmental variability in our oceans. From these records, we work to understand mechanisms driving natural variability in chemical, biological, and physical oceanography, along with the response of the ocean to anthropogenic climate change.
