How do interstellar ices give rise to molecular complexity in space?

Fascinated by the molecular universe and the chemistry that shapes it, my research explores how astrophysically relevant molecules interact with interstellar grains and ice surfaces. Using first-principles quantum chemistry, molecular dynamics, machine learning, and astrochemical modelling, I study binding energies, adsorption environments, and desorption behaviour in heterogeneous icy systems, to improve our understanding of astrochemical evolution in star- and planet-forming regions.
