In general, my research interests focus on the field of qualitative theory of dynamical systems, either with continuous time, or with discrete time. In particular, I am especially interested in using computer algorithms together with topological methods for investigating invariant sets of dynamical systems. A theoretical tool that proves to be useful for this purpose is the Conley index (a generalization of the Morse index, based upon the notion of an index pair). With the use of rigorous numerical methods (interval arithmetic, etc.), it is possible to construct index pairs built of n-dimensional hypercubes, and then apply the homology functor to obtain easy to manipulate algebraic information. The desire to be able to compute the homological Conley index effectively is my main motivation for diving into computational aspects of cubical homology theory.
