My research agenda has two prominent directions: algebraic topology and matroid theory.
As an algebraic topologist, I enjoy studying spaces of manifolds and cobordism categories. A recurring theme in this direction is the application of homotopy-theoretical methods to explore questions about manifolds.
On the other hand, within matroid theory, the current focus of my research is to study matroid invariants (e.g., the Tutte polynomial) via the machinery of cut-and-paste K-theory, a novel variant of K-theory that provides a framework to study decompositions of combinatorial objects from a homotopical point of view.
