Biography
I am a Royal Society University Research Fellow in the Quantum Light and Matter (QLM) group in the Department of Physics at Durham University. My research focuses on quantum science with ultracold atoms and molecules, using optical tweezer arrays—tightly focused laser beams capable of trapping individual atoms or molecules – to control and study these individual quantum particles. Using this newfound control, I aim to develop new platforms for exploring novel quantum materials and developing next-generation quantum sensors.
In 2025, I began my Royal Society University Research Fellowship, establishing my own research group to develop a new experimental platform based on tweezer arrays composed of two distinct atomic species. This project aims to leverage their unique properties for quantum simulation of strongly interacting quantum systems and new modalities for quantum sensing. Alongside this, I am a co-investigator on the EPSRC-funded project “Enhancing molecular control using Rydberg atoms”, where I explore how hybrid systems of molecules and Rydberg atoms can be used to advance the control and detection of ultracold polar molecules.
