Arianna Krinos is a final-year PhD candidate in Biological Oceanography in the MIT-WHOI Joint Program. Her primary area of research emphasis is protistan physiology and ecology. To understand protists, she uses modeling techniques (allocation modeling and ecosystem modeling, e.g. the Darwin-MITgcm model), physiology experiments, and bioinformatics. She is particularly interested in how protistan genetic diversity determines their ecosystem roles. She is currently working on projects on strain diversity in the haptophyte Emiliania huxleyi and improving the accuracy of taxonomic annotation in meta-omic datasets. Arianna is committed to education and sees her teaching and mentoring equal in importance to her research.
