Jonathan DeWitt

I am an NSF postdoc at the University of Maryland specializing in smooth dynamics. I earned my PhD under the supervision of Amie Wilkinson and Aaron Brown.


  1. Local Lyapunov spectrum rigidity of nilmanifold automorphisms
    Journal of Modern Dynamics 17 (2021): 65-109.
  2. Simultaneous linearization of diffeomorphisms of isotropic manifolds
    To appear in JEMS.
  3. Periodic data rigidity of Anosov automorphisms with Jordan blocks
    Preprint (2022).
  4. Cocycles measurably conjugate to unipotent over hyperbolic systems
    Preprint (2022).

During the summers of 2017 through 2020, along with N. Mayer, L. Mazurowski, and M. Neaton, I organized a math subject GRE preparation session for participants in the UChicago REU.
