My interests are in the areas of complex dynamics (in one or several variables), analysis, topology and the interplay between these fields. My research is focused on the study of complex Hénon maps, which are a special class of polynomial automorphisms of $\mathbb{C}^2$ with chaotic behavior. I am interested in understanding the global topology of the Julia sets $J$, $J^-$ and $J^+$ of a complex Hénon map. I am also interested in understanding the dynamics of maps with non-hyperbolic behavior such as Hénon maps or more generally holomorphic germs of $(\mathbb{C}^2,0)$ with a semi-indifferent fixed point. Some specific topics that I work on include: relative stability of semi-parabolic Hénon maps and connectivity of the Julia set $J$, regularity properties of the boundary of a Siegel disk of a semi-Siegel Hénon map, local structure of a non-linearizable germ of $(\mathbb{C}^2,0)$ with irrational rotation number.
