Visiting Assistant Professor at Williams College.

I'm interested in differential geometry (pseudo-Riemannian, Lorentzian, symplectic) and dynamical systems (smooth dynamics, magnetic flows, hyperbolic systems).

• Notes on Lorentz Geometry (curves and surfaces), later expanded to a full book published by Chapman & Hall/CRC.
• Notes for a summer mini-course in Symplectic Geometry I taught at The Ohio State University.
