Teaching
See CV for more on my teaching experience. If you contact me by email, I will be happy to give you more information and access to my materials. For example I prepared a complete set of online teaching materials for a service level ODE course (Math 53 at Stanford, taught twice, both with >100 students). It's a bit hard to share here. I also have lecture notes for a graduate level course on symplectic geometry and a topics course on Hamiltonian Floer theory . These are less polished, as I taught them only once.
