biogeochemistry + ecology

About Me

I am a marine scientist working at the intersection between biogeochemistry and ecology to explore ecological and environmental drivers of coral reef scale calcification. I employ these tools across colony to whole-reef spatial scales and annual to decadal time scales to better understand coral reef growth responses to climate change and human impacts. Currently, I am an Oceanography PhD student in the SCOOBY research group at Scripps Institution of Oceanography with my free time spent surfing and exploring Southern and Baja California.

Research

Under the current century of human-induced climate change and local impacts, how will coral reef growth and the ecosystem services coral reefs provide to humanity be impacted? 

 

Can we predict the future form and function of coral reefs under increasing seawater temperatures, decreasing seawater pH, and changing local impacts? 

 

My research integrates field measurements, publicly available data, and conceptual models to evaluate the growth and maintenance of coral reef structures in a changing world.
