🎉 I've been featured as one of 21 Early Career Investigators in the Journal of Natural Products 2026 Collection!

My work bridges quantum chemistry and pharmacognosy: asking computational questions about why natural products like hypericin behave the way they do as photosensitizers. Niche? Yes. Worth it? Absolutely.

#QUICHE is one of the particularly innovative passion projects we are proud to be involved in. It was therefore a great pleasure to visit our collaboration partners at Quantum Motion and Riverlane in the UK and gain first-hand insights into their fascinating cutting-edge #QuantumComputing technology.

A big thank you for the warm hospitality and the inspiring exchange - let’s continue shaping the future together!

`In this paper, we show a quantum simulator system that consists of a continuously driven Kerr parametric oscillator with a third-order nonlinearity that can be operated in the quantum regime to create a fully tunable asymmetric double-well. Our experiment leverages a low-noise, all-microwave control system with a high-efficiency readout, based on a tunnel Josephson junction circuit, of the which-well information.`

Circuit spotlight: VQE — H₂ Ground State

Parameterized quantum circuit + classical optimizer → molecular ground-state energy.

For H₂: 2 qubits, 4 parameters, converges to -1.137 Hartree — near the exact FCI/STO-3G result. Only 2 measurement bases needed (ZZ and XX).

Molecular Physics Early Career Researcher Prize 2024 — the official profile article is now out! 🎉

The awarded paper focused on advanced quantum-chemical calculations for predicting bond lengths and vibrational frequencies — well outside my primary field of medicinal chemistry. I’m grateful this work has been recognised internationally. 💪

New preprint https://arxiv.org/abs/2511.06957

A #perspective discussing Moreau-Yosida (MY) techniques in #densityfunctionaltheory.
MY regularisation has enabled to import tools from #convexanalysis into #dft
providing a new mathematical understanding of the most important atomistic simulation approach
and new robust algorithms for Kohn-Sham #dft.

Thanks to my co-authors from the #hylleraas centre and #oslomet for insightful discussions.
