About Me

Technical leader with a track record of shipping machine learning / AI solutions at scale. I love building things people use, and I’m passionate about interdisciplinary research and application. Currently, I am leading teams working at the crux of computer vision, natural language understanding, and graph machine learning.

When I am not thinking about graphs and transformers you can find me snapping shots on my Yashica T4 Super D, hiking, and making pottery.
