Hello 👋

I’m a grad student at the MIT Media Lab and Research Affiliate at the Stanford Digital Economy Lab. I study networked systems of humans and AI — how they coordinate, how they make decisions, how detectable and steerable they are — and what that tells us about the future of social networks, digital markets, and hybrid organizations.

Before that, I:

  • worked as a software and ML engineer at two AI startups, where I trained language models and built pipelines around them

  • got my Bachelor’s degree from Columbia University, where I double-majored in Computer Science-Statistics and Psychology

  • produced music professionally for +5 years.
