Research Interests: My current research comprises the fields of holomorphic dynamical systems of one and several complex variables, conformal iterated function systems and smooth dynamical systems. This research also overlaps and has applications to fractal geometry, number theory and potential theory.

The research in the field of holomorphic dynamical systems of one complex
variable focuses mostly on the geometry and ergodic theory of transcendental entire (including exponential) and meromorphic (including elliptic) functions as well as on the questions of structural stability.

My research in the field of holomorphic dynamical systems of several complex variables mostly concerns with the applications of the inverse thermodynamic formalism to the dimension problems of holomorphic endomorphisms satisfying Axiom A.

The theory of infinite iterated function systems developed within last ten years jointly with Dr. Mauldin is being currently applied to the problems coming from holomorphic dynamics, smooth dynamics and Diophanitne approximations. This theory is still studied itself especially in the contexts of families of such systems and graph directed Markov systems.

In the area of smooth dynamical systems I am concentrated on geometry and dynamics of Smalle's horseshoes exhibiting parabolic type phenomena.
