I am a PhD candidate and junior researcher in Bayesian computation under the supervision of Prof. Krzysztof Latuszynski and Prof. Gareth Roberts. My goal is to contribute to the development of computational methodology that enables exact Bayesian inference for complex inference problems in the sciences and AI. I also bring an applied perspective to my work due to my background in Economics and my industry experience as a Data Scientist. That perspective informs my interest in translating methodological research into plug-and-play tools that are accessible to other researchers.
