Author note: There is a very interesting conjecture here on non-existence of sky catastrophes for Reeb vector fields, and for which I welcome aid.

K-theoretic invariants of Hamiltonian fibrations, (with Egor Shelukhin), Journal of Symplectic Geometry, Vol. 18, No. 1 (2020), pp. 251-289.

This introduces some new K-theoretic quantization techniques for Hamiltonian fibrations, and uses this to deduce some new results on topology of Ham(CPn).
