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.
This semester I am teaching two courses. The first is an advanced lecture course on quantum mechanics (via symplectic geometry). Lecture notes (which are continuously being updated) can be found on my teaching page. The second is a seminar on stable commutator length and quasimorphisms.
My wife, Irida Altman, is also a mathematician. You can find her (non-mathematical) webpage here.
