Culturing phytoplankton under trace nutrient limitation
In the Saito Lab at the Woods Hole Oceanographic Institution, I grew a keystone Antarctic phytoplankton species, Phaeocystis antarctica, under iron and vitamin B12 stress conditions to test the interactive effects of multiple limiting nutrients.
Measuring proteins & METAls
Learning from the expertise of the Saito Lab, I grew, harvested, and analyzed the protein and metal content in Phaeocystis antarctica cultures that were exposed to a range of high and low iron and B12 concentrations.

In prep. Phaeocystis antarctica morphotypes respond differently to iron and B12 stress conditions.
Phaeocystis antarctica colonies from the Amundsen Sea, Antarctica. These colonies were collected from a surface net tow and hand-pipetted into smaller volumes. These colonies were especially large and were a few millimeters in diameter! Photos taken with my cell phone.
