Postdoctoral Fellow at Mila – Quebec AI Institute, co-supervised by Yoshua Bengio and David Rolnick.

During my post-doc I developed AI systems to reduce carbon emissions from buildings—which account for ~37% of global CO₂ emissions. My research focuses on graph-structured world models and reinforcement learning, with an emphasis on systems that generalize (for example, across different building types, network layouts, and environments). Previously I studied causal inference and Bayesian methods for decision-making.

My work sits at the intersection of model-based RL, graph neural networks, and the physical world. I'm particularly interested in how we can learn generalizable physics from simulations.
