Dieter Hendricks

Senior Machine Learning Scientist

Dieter's research lies in the domain of computational and mathematical finance. Key interests include understanding high frequency market microstructure, dimensionality reduction and optimal control in complex adaptive systems. His PhD work developed techniques for online learning in high-frequency financial markets, focusing on scale-specific state representation and constrained interaction under a reinforcement learning paradigm.

Dieter's current role involves working with the BNP Paribas Capital Markets quantitative research team, where they are investigating the use of probabilistic generative models for client recommendations to assist sales traders. Another project considers the nature of adverse selection in OTC markets and how this may be accounted for in market making. Within the Machine Learning Research Group, Dieter is working on projects which explore the nuances of applying state-of-the-art machine learning techniques to market microstructure problems. A key focus is on dimensionality reduction for limit order books and data-driven approaches to eliciting effective reward functions/agent objectives at different hierarchies or scales of intraday microstructure.
