Professor Lizotte's research aims to adapt and improve reinforcement learning, machine learning, and statistical techniques so they can be applied to new sources of medical data, and can in turn provide clinicians with the best available evidence for non-myopic medical decision making. He is particularly interested in problems involving multiple outcomes, causal inference, and outlier detection.
