Professional Summary

I develop machine-learning methods for atomistic simulation, with a focus on uncertainty quantification. I am interested in determining when a model’s predictions can be trusted and when they cannot, which is a question central to deploying ML reliably in the physical sciences. I am also involved in the development of universal machine learning potentials. I have developed the universal PET-MOLS model and applied it to study amorphously formulated active pharmaceutical ingredients. I also build deep-learning models for predicting NMR chemical shieldings (ShiftML), which I make available to the wider chemistry community.
