My research interests are in geometry, particularly problems motivated from mathematical physics. A common theme to my research is various moduli space problems. My most recent papers are
A new cohomology class on the moduli space of curves.
where we construct a cohomology class on the moduli space of curves which naturallu pairs with any cohomological field theory.
Topological recursion with hard edges.
joint with Leonid Chekhov where we prove a Givental type decomposition for partition functions that arise out of topological recursion into products of Konstevich-Witten and Brezin-Gross-Witten KdV tau functions.
Topological recursion on the Bessel curve.
joint with Norman Do where we describe an analogue of the Airy curve which describes local irregular behaviour of spectral curves.
Primary invariants of Hurwitz Frobenius manifolds.
joint with Dunin-Barkowski, Orantin, Popolitov, Shadrin where we obtain the primary invariants of a Hurwitz Frobenius manifold via periods of a differential along cycles on the domain curve, generalising the construction of flat coordinates via periods.
Dubrovin's superpotential as a global spectral curve.
joint with Dunin-Barkowski, Orantin, Popolitov, Shadrin where we apply topological recursion to a spectral curve produced from any conformal Frobenius manifold via a construction of Dubrovin.
Topological recursion for Gaussian means and cohomological field theories.
joint with Jørgen Andersen, Leonid Chekhov and Robert Penner which proves integrality results for coefficients coming out of the Hermitian matrix model.
Quantum curves and topological recursion.
which is a survey article on quantum curves. See my research interests and papers in the side menu for more.
