Alanna Hoyer-Leitzel

I am an 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.

Research

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.
