Marta Grześkiewicz is a College Associate Lecturer and Fellow in Economics at St John’s College, University of Cambridge. She holds a BA in Economics from the University of Cambridge and an MSc in Data Science and PhD in Statistical Science from University College London (UCL).

Her research interests lie at the intersection of economics and machine learning. Her current projects involve developing algorithms to model choice and decision-making by economic agents, with applications in industrial organisation (demand estimation, revenue management, and dynamic price optimisation), agent-based modelling with machine learning in banking and finance, and the integration of economic theory into machine learning models for economic forecasting.

She has taught across economics, machine learning, and statistics at both UCL and the University of Cambridge, including designing and delivering a lecture course on Multi-agent Reinforcement Learning and Agentic AI at the Department of Physics, University of Cambridge. She has prior experience in investment banking, as a machine learning researcher, and has previously founded her own VC-backed start-up.
