My main research interests are Berezin-Toeplitz operators, that one encounters one studying the semiclassical limit of geometric quantization, and classical and quantum integrable systems, in particular semitoric systems.

Here is an animation of the joint spectrum when the parameter t varies; the red line is the boundary of the image of the momentum map,
the critical value which transitions from elliptic-elliptic to focus-focus corresponds to the black circle, and blue dots are joint eigenvalues. Here R1 = 1, R2 = 5/2 and k = 5.
