About Me

I am a postdoctoral fellow hosted by Prof. Leonardo T. Rolla at Instituto de Matemática e Estatística da Universidade de São Paulo. Before that, I was a postdoc hosted by Prof. Gidi Amir and Dr. Naomi Feldheim in Bar-Ilan University, hosted by Prof. Tertuliano Franco in UFBA, and a Ph.D. student under the supervision of Prof. Hubert Lacoin at IMPA. Here are my CV and thesis: Mixing time for interface models and particle system (slide).

I am mainly interested in the intersection between probability theory and statistical mechanics. In particular, my research focuses on Markov chains and mixing times, random polymer models, interacting particle systems, random walks in random environments, Gaussian random functions, etc.
