Math 490 Mathematics of Machine Learning in Fall 2022 is online and on
Canvas. Zoom info will be posted on Canvas and sent before the
first class meeting to everyone who is registered and to auditors who
email with enough time for my response. For exact details about this
course, please refer to Canvas. For an approximate sense of how this
course will go, you can look at the public Fall 2019 Math 490 webpage:

Condensation and Biological Machines.
I'm also interested in:
Working with a student who is fluent in quantum mechanics and German.
Quantum groups as models of freely independent random
variables, especially in non-tracial von Neumann algebras.
Quantum statistical mechanics models:
Bose-Einstein condensation and nonlinear Schrödinger
equations (NLS), discrete NLS and other lattice systems with noise or long-range interactions, and fractional NLS models of energy transport in biopolymers like DNA. Terry
Tao's blog entry about some of my BEC work.
Classical statistical mechanics: soft-sphere models of plasmas, and the Landau equation in the weak coupling limit.
Computational probability, algorithms, and family genetic data
models of ferromagnets and superconductors: Heisenberg
model, XY model,
coupled XY models, Toy Higgs model, other O(N) models, and connections with
macroscopic equations for magnets and superconductors, especially
I've mentored Illinois
Geometry Lab projects on percolation
theory with Michelle Delcourt and Thomas Mahoney, and a
project on phase transitions in XY models with Tayyab Nawaz.
