I earned my PhD in Chemical Engineering at the University of California, Berkeley (2021). My doctoral studies focused on the fundamental mechanisms behind metal-catalyzed hydrogenation reactions and the synergies between metals and metal oxides.

From 2022-2025, I worked as a postdoctoral research fellow at Nanyang Technological University in Singapore. I applied multiscale modelling, computational chemistry tools, and mechanistic inquiry to explore the nature of oxidation reactions driven by ultrasound.

In the Fall 2025, I joined the Laboratory for Chemical Technology at Ghent University in Belgium as a postdoctoral research fellow.
