Schematic of a heavy-metal complex and interacting electronic configurations

01 / Strong correlation and heavy metals

Quantum methods for correlated and heavy-metal systems

Strongly correlated molecules and heavy-metal complexes pose demanding electronic-structure problems. Several electronic configurations may contribute to their behavior, and heavy elements can introduce significant relativistic effects. I am interested in quantum algorithms that capture these features accurately while keeping circuit depth and measurement costs practical.

02 / Excited-state quantum algorithms

Reliable molecular excitation energies

Electronic excited states help explain how molecules absorb light and undergo photochemical reactions.

I develop and assess quantum subspace methods for predicting excitation energies, focusing on accuracy, measurement cost, error mitigation, and numerical stability.
