Research

My PhD is focused on developing algorithms, architectures and abstractions for endowing neural networks with a human-like understanding of the world. To this end, I focus on key tenets of human intelligence, i.e., data-efficiency, compositional generalization, counterfactual thinking, long-context understanding and interpretability.
