I am currently a postdoctoral researcher in the European Research Council (ERC) Starting Grant (Ocean Glow) led by Thomas J. Browning.
The overall goal of Ocean Glow is to better understand what regulates marine primary productivity through a deeper investigation of the natural fluorescent light emitted by phytoplankton.
My role in this project is to implement a novel facility of trace metal clean mesocosms to perform highly-controlled experiments and test the fluorescence of four, globally relevant types of phytoplankton under different nutrient conditions.
