Research Interests

My research interests include studying how climate change affects ecosystem stability. In particular, I am interested in how wide-spread hypoxic and anoxic conditions are formed and how they impact ecosystems. My thesis research under Dr. Dale Haidvogel focuses on what led to the oceanic anoxic events during the Cretaceous and how these events affected the lower trophic levels during this time period.

Short History

Originally from Virginia, I moved to South Carolina to pursue dual degrees in applied math and marine science at Coastal Carolina University. During my time at Coastal, I had many opportunities, including working as student coordinator for the South Carolina Marine Mammal Stranding Network, and working as a lab technician at the Environmental Quality Lab. I also had multiple opportunities to be involved in conservation work with sea turtles. As I continued my math studies, I became increasingly interested in modeling ocean phenomena, leading me to develop a model of Long Island Sound as my undergraduate thesis project. This inspired me to pursue my current studies in modeling climate change.
