Currently I am learning symplectic topology/geometry with Eleny Ionel.
Rumor has it that I used to be interested in number theory in the past.
In Winter 2013 I am a TA for Math 52. My office hours on Wednesday, March 13 are 11:50-1:15pm, 2:05-3pm and 4:15-5:15pm.
You can find the examples done in the first five sections here.
Notes for Math 257A: Introduction to Symplectic Topology, Fall 2012, taught by Eleny Ionel (work in progress).
The final project for the "Quantum Mechanics for Mathematicians" course (a.k.a. Math 273A) taught by Leonard Susskind (Fall 2012): using a finite dimensional approximation to calculate low energy eigenvalues and eigenstates of the quantum harmonic oscillator.
