About Me

I'm a tenure-track scientist at the Laboratory for Simulation and Modelling (LSM) at the Paul Scherrer Insitute (PSI). Before taking up this position at PSI, I was a post-doctoral researcher at the Chair of high performance numerical algorithms and simulations (HPNALGS) at EPFL under the supervision of Laura Grigori. Prior to moving to EPFL, I was a post-doctoral researcher at the Laboratoire Jacques-Louis Lions under the supervision of Yvon Maday. Along with several of Yvon's students and collaborators, I worked on the Extreme-scale Mathematically-based Computational Chemistry ERC Synergy project. Before taking up my post-doctoral position at the LJLL, I studied at RWTH Aachen and ETH Zürich. I wrote my Phd Dissertation under Benjamin Stamm, and before that my MS thesis under Sid Mishra.

Research Interests

The main part of my research involves the numerical analysis of state-of-the-art wave-function methods that are used to solve the electronic Schrödinger equation. My post-doc at EPFL involved the analysis of the DMRG algorithm for computing the ground states of strongly correlated molecules while my post-doc at the LJLL focused on the analysis of coupled cluster methods for computing the ground states of dynamically correlated molecules.

In a joint project with Eric Cancès and some colleagues at CERMICS (Ecole des Ponts), I also work on band structure calculations of crystalline materials. Additionally, together with Jean-Philip Piquemal and my former colleagues at the Laboratoire de Chimie Théorique (Sorbonne Université), I work on adaptive variational quantum eigensolvers.

During my Phd, I mostly worked on the mathematical analysis of boundary integral equations and domain decomposition methods with applications in polarisable electrostatics.
