I am a researcher at Sandia National Laboratories in Livermore, CA, working on semiclassics, quantum information, and complexity theory using algebras with associated (discrete) symplectic phase spaces.

Much of my interests lie in connecting semiclassics and path integral expansions in terms of Planck's constant with the computational complexity of problems. This involves topics such as the Wigner-Weyl-Moyal formalism, discrete Wigner functions, van Vleck propagation, the Clifford subtheory and quantum contextuality.

I blog about some of my research, quantum information, and physics in general here.
