About
I am a postdoctoral researcher in the High Performance Numerical Algorithms and Simulations (HPNALGS) group at EPFL, working with Prof. Laura Grigori.
I received my DPhil in Mathematics from the University of Oxford in 2025, where I was a member of the Numerical Analysis group and was supervised by Prof. Yuji Nakatsukasa.
Research Interests
My research is in numerical linear algebra, with particular interests in
- randomized algorithms for matrix computations,
- matrix perturbation theory,
- low-rank approximation.
My work focuses on developing fast, accurate, and reliable algorithms for large-scale matrix computations.
