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.
