Researcher. Distyl AI

My research aims to empower users to: i) depend on data-driven decisions; and ii) simplify data-centric workflows. I focus on the architecture and implementation of data systems and tools. The goal is to make them more efficient and robust, and to enable new use cases through interface design.

I am interested in building usable systems and try to make my work open-source. Previously, I worked on GraphflowDB, a research prototype, and on its successor Kùzu, a spinoff from the University of Waterloo. I work as a researcher at Distyl AI and get to think about research problems starting from product requirements.
