Recently, I co-taught a summer graduate workshop at MSRI on the geometry of tensors; the link includes video of some of the lectures.
In past semesters at Berkeley, I have been the GSI for Math 256A (Algebraic Geometry), Math 250B (Commutative Algebra), Math 127, and Math 1b (Calculus), and the instructor for Math 16A in Berkeley Summer Sessions. I was also a GSI for Principles of Economics at the University of Michigan.
