About me
I am an MSCA Postdoctoral Fellow at UiT The Arctic University of Norway in Tromsø, in the Department of Mathematics and Statistics and associated to the Lie-Størmer Center. Since September 2026, I have been working on the project PRISM, hosted by Cordian Riener. I am on leave from my position as assistant professor (non-tenure-track) at the University of Klagenfurt, where I work with Angelika Wiegele.
I obtained my PhD from Tilburg University in 2022 as part of the MINOA project, under supervision of Etienne de Klerk and Monique Laurent. My thesis is Symmetry Reduction in Convex Optimization with Applications in Combinatorics.
A more detailed CV is available online.
Research interests
I study conic optimization for highly symmetric problems, investigating computational and analytical ways to exploit symmetries. In particular, I am interested in
Semidefinite and polynomial optimization,
Symmetry reduction and representation theory,
Algorithms for conic optimization, and
Computer-assisted proofs in extremal combinatorics and discrete geometry, including flag algebra methods.
PRISM
My MSCA Postdoctoral Fellowship, PRISM: Graph Profiles via Invariants, Sums-of-squares and Moment methods, develops symbolic and semidefinite methods for certifying boundaries of polynomial images and graph profiles. The project combines polynomial optimization, real algebraic geometry, representation theory and extremal combinatorics. It started on 1 September 2026 at UiT, with a planned four-month secondment with Oleg Pikhurko at the University of Warwick.
