Research Interests

My research focuses on understanding the effects of the quantum mechanical nature of the nuclei (i.e. tunneling and zero-point energy effects) at the atomic level using state-of-the-art computer simulations. Nuclear quantum effects impact the stability of substances (e.g. ice) and can dominate chemical reaction mechanisms and rates. In specific:

• Ab initio path-integral molecular dynamics (PIMD) simulation of hydrogen-bonded systems.

• Development and application of quantum thermal & microcanonical reaction rate theories based on instanton theory.

• Understanding the importance of heavy atom tunnelling in non-adiabatic electron transfer reactions and spin transition reactions.

• Application of Machine learning approaches to molecular simulations.
