About

I'm a graduate student at the Massachusetts Institute of Technology (MIT), where I study the nonlinear dynamics and complexity of earth and planetary systems with Dr. Daniel Rothman. From 2022 to 2023, I also developed hydrodynamical, inverse, and numerical models of noble gas tracers to constrain the global ocean heat budget with Dr. Alan Seltzer and Dr. David Nicholson through the MIT and the Woods Hole Oceanographic Institution (WHOI) Joint Program in Oceanography. Previously, I was an undergraduate at the University of Chicago (UChicago) where I earned a B.S. in Applied Mathematics and a B.A. in Physics in June 2022. During undergrad, I worked with Professor David Archer in the Department of Geophysical Sciences at UChicago and under Dr. Ken Buesseler and Dr. David Nicholson at WHOI. In both groups, I developed data-constrained oceanographic models.
