As a post-doc at Imperial College I taught the Advanced Dynamical Systems course in the Spring term of the year 2017-18 at the MSc level. We covered the theory of circle homeomorphisms and diffeomorphisms from rotation theory to Arnol'd's KAM theorem.
My last year as a PhD student I held an ATER position (Temporary Position for Teaching and Research) in Université Paris 6, and I did TA for Introduction to Topology and Differential Calculus (3rd year) and for Vector Calulus and Multiple Integrals.
As a PhD student, I held a TA position in Université Paris 12 and did TA for Algebra, Linear Algebra (1st and 2nd year), Sequences and Series of functions (3rd year) and Mathematical Tools for Biology (1st year).
