Teaching Experience

I have taught several undergraduate Physics and Mathematics classes at UFABC from 2009 to 2019, including Classical Mechanics, General Relativity, Multivariate Calculus, Linear Algebra, Complex Functions and Differential Geometry. I have also had fun teaching graduate level short courses: Black Hole Quasinormal Modes (CBPF, Brazil, 2018), Neutron Star Asteroseismology (University of La Plata, Argentina, 2019) and Neutron Stars (Fermi Summer School, Delaware, 2022).
