I was a predoc researcher in mathematics both at ICMAT and Université de Rennes 1, under a joint supervision of Yago Antolín and Rémi Coulon. My research area was geometric group theory.

I was interested in the study of exponential growth rates in groups of non-positive curvature. The techniques I exploited included simple counting arguments; metric inequalities and geometric small cancellation theory. In particular I studied groups acting properly with a contracting element and groups acting acylindrically on hyperbolic spaces. I was also interested in monster groups.
