Biography

I am a biological oceanographer working as a research scientist at the University of Washington. I study how microbial communities respond to environmental perturbations and ultimately how they will respond to future ocean conditions. My research approach uses flow cytometry observations collected from research vessels across ocean basins to build population models that predict cell, population and ecosystem interactions.

Featured Project

Computational Flow Cytometry Analysis of Marine Phytoplankton

Since 2010, the shipboard underway cytometer SeaFlow has been operated for 17,000 hours across 175,000 km of ocean, collecting over 350,000 samples in surface waters.
