My research spans mathematical physics, quantum field theory, topology, string theory, gravitation, and mathematical methods. Below is a selection of current and previous research projects developed in collaboration with researchers around the world.
Current Research
Rigorous Construction of Abelian Chern–Simons Theories
Topological Quantum Field Theory · Chern–Simons Theory · Tsinghua University
As part of my PhD research, I established a symmetric monoidal natural isomorphism between toral Chern–Simons theories and the corresponding Reshetikhin–Turaev theories. This gives an equivalence of extended (2+1)-dimensional topological quantum field theories and leads to a classification of extended Abelian Chern–Simons theories.

Previous Research
Matrix Models and Topological String Dualities
String Theory · Matrix Models · ICTS-TIFR · 2023–2024
I studied closed-string duals of Hermitian matrix models in the conventional ’t Hooft large-(N) limit, with the goal of establishing an explicit correspondence with a mirror pair of closed topological string theories. I also studied connections between Gromov–Witten theory and the Gaussian matrix model.

Electroweak Radiative Corrections in Semileptonic Kaon Decays
Quantum Field Theory · Standard Model · University of Bonn · 2019–2022
As part of my master’s research, we developed a new theoretical framework for one-loop electroweak radiative corrections in effective field theories and applied it to precision studies of semileptonic kaon decays.
