In Paris I have TA'ed two semester courses: Analysis and Topology in R^n, and Functional Analysis.
In São Paulo, I served as a teaching assistant for a few undegraduate courses at USP: Calculus II for Engineering, Differentiable Functions and Series, Real Analysis for Math Education and Introduction to Algebraic Topology.
In all of my undergraduate years I participated at the S4 seminar, which is a student run seminar for freshmen, whose goal is to introduce advanced Mathematics in a simpliefied way. In 2021, I started an academic group, the A5 Group, wich organizes seminars and events for Undergraduate and Master students. Our aim is to introduce research level math for students at IME.
