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

I develop 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 for HVAC control, with an emphasis on building transferable systems that generalize across different building types, layouts, and climates. Previously I studied causal inference and Bayesian methods for decision-making, in the context of indoor air quality and energy use in cities.

My work sits at the intersection of graph neural networks, model-based RL, and building physics:

• Graph Dreamer — A world model architecture for variable-size, heterogeneous graph environments that learns structural relationships governing thermal dynamics, enabling zero-shot transfer across buildings with different topologies
• HVAC-GRACE — Graph-based Bayesian forecasting and control for buildings
• HOT Dataset — A dataset of ~150,000 simulated controllable buildings and gym for transfer learning research

I'm particularly interested in how we can learn generalizable physics from simulations

Most of my recent code lives in private repositories (pre-publication research), but I'm working on releasing components as papers are published.
