About

I believe the right way to solve a problem emerges from a good representation of the problem itself. My work is about finding the optimal way to express systems: physical systems as differentiable computing structures, neural networks as physical systems, physical systems as neural networks, and physical systems as text. Across nanophotonics, scientific machine learning, optical instrumentation, and autonomous design, I look for representations that make complex systems easier to optimize, interpret, and build.
