About me.

I am a postdoctoral fellow at NORDITA in Stockholm. Originally from California, I completed my PhD in applied physics at Northwestern University with a focus on discovery and diagnosis of topological quantum matter. I am motivated by both practical problems and abstract mathematical concepts. I enjoy building computational tools, generally incorporating AI and density functional theory with the help and guidance of amazing collaborators around the world.

In my free time I love to travel and run long distances. I have run more than 25 marathons with a personal best of 2:28. I have also run a number of 100k ultra marathons. If you are interested in learning more about my work or collaborating please feel free to reach out.
