Teachings and Notes

Courses at CMU

As lead TA I coordinate the TAs and design handouts and quizzes. As lead TA, and TA I teach recitation sections. As a grader, a TA, and lead TA, I hold office hours and run review sessions.

Mathcamp

Over the Summer I have taught at the Canada/USA mathcamp. I designed and taught the following courses:

  • Insert Geometry Joke Here: An introduction to non-euclidean geometries and surfaces. The goal of the class was to develop visualization skills for hard to grasp spaces.
  • Sit Down and Don't Solve SAT: A course focused on learning reductions to the SAT problem. This included an introduction to complexity classes, reductions, and Turing Machines.
  • Archers at the Ready: A more fast paced course focused on understanding the basics of homological algebra and why it is useful.
  • Ultra-fantastic Ultra-filters: A course introducing ultra filters, proving that they exist, and using them in a Ramsey theoretic setting.
  • Party Parrot Workshop: An IBL course that introduced wall-paper patterns, fractals and holomorphic deformations and then encouraged campers to play with these concepts as applied to a popular emoji around camp (the party parrot).

I also ran the following camper projects:

  • Hirsch Conjecture Reading Group
  • Student Lead Class: Mathematical Realism
  • Student Lead Class: Spectral Graph Theory
  • Escher Illusions Realized: See the creation of this work that camper Eleni Persinger created in minecraft!
