William Clements

Senior Machine Learning Researcher at indust.ai

I am a senior research scientist at indust.ai in Paris, France, working on bridging the gap between the academic state of the art in machine learning and industrial needs. My current research focuses on developing new methods for applying reinforcement learning to real-world problems.

I am also a physicist by training, and my PhD work focused on quantum optics and quantum information processing.
