I am the Kennedy-Schelkunoff Assistant Professor of Mathematics at Mount Holyoke College. Previously I was an Ed Lorenz Postdoctoral Fellow at Bowdoin College, funded by MCRN. I graduated from the University of Minnesota with my PhD in Mathematics in July 2014.

TeachingSpring Semester 2019 Syllabi for previous semesters
Student Course/Teaching Evaluations Resource
Dynamical Systems and applications of dynamical systems to physical problems; relative equilibria in the n-vortex problem from the perspective of Hamiltonian dynamical systems; bifurcations, tipping, and disturbance in dynamical systems, especially applications related to resilience and climate. I also know a tiny bit of computational algebraic geometry.

My advisor is Rick Moeckel.
I did my postdoc with Mary Lou Zeeman. A few of my favorite collaborators:
