Building agentic AI systems at NatureAlpha

About Me

I build things
that think.

I build agentic AI systems at NatureAlpha, designing and deploying LLM-powered pipelines for sustainable finance data. Previously, I was a Research Engineer at dunnhumby working on customer data science, and a Research Assistant at Singh Lab using deep learning to study ageing biology. I hold an MSc in Data Science and a BA in History from Brown University.
