Research Interests

My research interests focuses on smooth Dynamical Systems (topological, geometrical and statistical aspects). My research it deal about global impacts of local bifurcations (“butterfly effect”) of the dynamical systems. I am especially interested in the generation of robust non-hyperbolic dynamics (heterodimensional cycles and homoclinic tangencies), via bifurcations of heterodimensional cycles in high regularity topologies. Extensions of the classic thermodynamic formalism for the non-hyperbolic setting is also one of my research interests/lines.
