About me

I'm a 4th Year PhD student at Brown University, advised by Lorin Crawford, and a Student Researcher at Google Deepmind on the Protein Function team in the Bay Area, CA. I work on biologically and physically inspired models, with a focus on learning meaningful, data-efficient representations for protein-knowledge problems.

I also spend time co-organizing a Machine Learning x Proteins seminar series and co-run after-school computational science workshops at Providence public schools with some of my wonderful peers.

I'm excited about the future of Machine Learning for scientific domains, especially in biology. My reading and work leans into the mathematical and algorithmic principles that we can use to explain structure and mechanisms in science. As I learn more about math and proteins, I'm trying to make notes and collect useful links. You can find notes here and interesting reads here. Some of the workflows that I've created as I've needed them can be found on my github.

Research Projects

• Logit Subspace Diffusion for Protein Sequence Design.
  With Nathan Frey, Andrew Watkins,and Jae Hyeyeon Lee.
