About

Technical depth, translated into action.

I am a Harvard undergraduate studying Physics and Economics, with interests spanning quantum information, scientific machine learning, cryptographic resilience, and technology strategy.

I am drawn to people and projects that are rigorous without being narrow—work that advances the frontier, creates leverage, and builds pathways for others to participate.
