As part of “The Breakdown,” RI C-AIM’s student newsletter, Diana Fontaine, doctoral candidate at URI’s Graduate School of Oceanography, talks about her background and research as a marine biologist with C-AIM investigator Dr. Tatiana Rynearson, her advisor.
My interest in marine biology began in a high school class during our dissection of a squishy sea cucumber. After realizing I could become a marine biologist, I decided to move across the country to pursue a degree in marine science at the University of San Diego. During the last two years of my undergraduate career, I worked in a larval ecology lab. Summertime meant keeping a close eye on tide tables to know when to collect my barnacle settlement plates in the rocky intertidal zone.
After graduation, I accepted a job as a plankton analyst in the Marine Invasions Lab at the Smithsonian Environmental Research Center (SERC) in Edgewater, MD. There, I spent two years studying phytoplankton in ballast water of cargo ships and gaining experience with phytoplankton taxonomy and culturing techniques. I then decided to go to graduate school and found myself back in my favorite place, New England, at URI Graduate School of Oceanography with Dr. Tatiana Rynearson.
As a second year doctoral student, my work involves using genetic techniques to study phytoplankton diversity (Rynearson et al. 2020). In collaboration with the Northeast US Shelf Long-Term Ecological Research site, I measure size-fractionated primary production rates across a spatial gradient from Narragansett Bay to the shelf-break. I am particularly interested in understanding how environmental stressors associated with climate change affect phytoplankton community dynamics and overall ecosystem function. I value science communication and enjoy my role as a student mentor and pen-pal in the Letters to a Pre-Scientist Program where I inspire youth to engage with science.
During my free time, I love making pottery and being outdoors either at the beach or in the mountains of New Hampshire.
