Kelsy Cain


Research Scientist

Both in the lab and at sea, I operate a BD Influx Cell Sorter and SeaFlow, an underway flow cytometer, to generate and analyze flow cytometry data of phytoplankton and bacterial communities. I assist with instrument testing and deployment of new flow cytometers being developed in the lab.
