About my research:

I am a graduate student in Brad Rosenheim’s Geochemistry research lab. My study focuses on analyzing sediment cores utilizing a Bayesian accumulation model to improve radiocarbon age models and chronologies. I am currently picking mixed planktonic foraminifera assemblages from specific depth intervals throughout my core for 14C determinations. I will test the hypothesis that a higher density of dates carrying less individual precision will lead to a more comprehensive age model by contrasting results with age models produced through traditional radiocarbon dating. The core I am investigating will be approximately 2000-6000 y old, and contains paleo-environmental information about the influence of the growing human population on Mississippi River sediment transport dynamics, potentially helping to answer questions about the terrestrial-marine carbon cycle in Northeastern America.

Why USFCMS?

I received my Bachelor’s Degree from The University of Tampa in Marine Science and Chemistry just over the bridge from St. Petersburg. I chose to attend the University of South Florida’s College of Marine Science due to the great collaboration with nearby institutions such as the USGS, FWRI, FIO, and NOAA. This area possesses a concentration of wise scientists and I believe it a hotspot in the investigation of the Deepwater Horizon oil spill that occurred half a decade ago. I was given the opportunity to become a teaching assistant and gained experience inside and out of the classroom preparing lectures and aiding in the construction of the Introduction to Oceanography online course. The city of St. Petersburg and the surrounding region provides many exciting activities when you find time outside the lab. I find it rewarding to spend a day relaxing on the beach, or going out on the boat to go wakeboarding or on a scuba diving adventure.
