Santiago Martinchich

I am an Assistant Professor (Profesor Adjunto) at Facultad de Economía y de Administración, Universidad de la República, Uruguay.

I was a postdoc at PEDECIBA (Uruguay) during 2023-2024. I completed my PhD in 2023 at Université Paris-Saclay and Universidad de la República under the supervision of Sylvain Crovisier (Paris-Saclay) and Rafael Potrie (Udelar). Here you can find my CV.

My email address is santiago.martinchich@fcea.edu.uy.

Research

My research focuses on dynamical systems, and interactions with geometry and topology. I am particularly interested in partially hyperbolic diffeomorphisms, Anosov flows, foliation theory, manifolds, and realated things.
