I'm currently working on products in Rabinowitz Floer homology, and on various questions related to orderability and contact non-squeezing. Also: a hyperkähler version of Rabinowitz Floer homology, a Novikov Floer homology for magnetic cotangent bundles, and Gromoll-Meyer type questions about leaf-wise intersections. For more information see my publications page.
Next semester I am teaching two courses. The first is an advanced lecture course on quantum mechanics (via symplectic geometry). The second is a seminar on stable commutator length and quasimorphisms. Lecture notes will eventually appear on my teaching page.
My wife, Irida Altman, is also a mathematician. You can find her (non-mathematical) webpage here.
