Academic Interests

  • Theory of deep learning
    • Inductive and spectral bias — which functions a model finds easy to learn, and why.
    • Generalization and scaling laws; implicit bias of modern optimizers.
  • Transformers and attention
    • In-context learning and the emergence of induction heads.
    • Feature learning and phase transitions during training.
  • Statistical physics of learning
    • Gaussian processes, kernel methods, and infinite-width limits.
    • Mean-field theory and the representation theory of symmetry groups.
  • Earlier work — high-energy phenomenology
    • Thermal dark matter and freeze-out beyond the WIMP unitarity bound.
