I'm interested in improving our understanding of machine learning systems and their generalization capabilities including:

• Interpretability: mech interp, representation science, data attribution
• Open-ended learning: self-play, open-endedness, unsupervised RL
• Mathematical foundations of ML: geometry of learning, optimization, deep learning theory

Previously, I was a YC founder at Clarum, building AI agents for private capital investing. I've also worked on high frequency trading at Tower Research and privacy preserving knowledge intersection at Optable.
