Research Interests

My research focuses on the deep connections between type theory, homotopy theory, and category theory, exploring how these frameworks provide new foundations for mathematics and connect to computational logic.

Homotopy Type Theory

Investigating the connections between homotopy theory and type theory, exploring univalence, higher inductive types, and new foundations for mathematics.

Category Theory

Studying categorical structures, ∞-categories, and their role in understanding mathematical foundations and the structure of mathematical objects.

Type Theory

Exploring dependent type systems, Martin-Löf type theory, and the computational interpretation of logical and mathematical constructions.

Synthetic Homotopy Theory

Developing synthetic approaches to homotopy theory within type-theoretic frameworks, enabling direct reasoning about homotopical structures.

Formal Verification

Applying type-theoretic methods to formal proof systems and computer-verified mathematics, bridging theory and computational practice.

Foundations of Mathematics

Examining fundamental questions about mathematical foundations, exploring alternatives to set theory and new axiom systems.

Topological Groups

My doctoral work focused on convergent sequence properties of topological groups across various compactness properties, studying the interaction between algebraic and topological structures.

Current Work

These areas represent an ongoing exploration of how modern mathematical frameworks can provide deeper insights into the nature of mathematical truth and computation. The intersection of homotopy type theory and computer science offers exciting possibilities for both pure mathematics and practical applications in formal verification, proof assistants, and the foundations of programming languages.
