Currently: I am a Machine Learning Research Scientist at Altos Labs in San Diego. At Altos, my research program aims to develop ML methods that accelerate the process of scientific discovery in molecular biology, with an emphasis on spatial data and representation learning.

Research Interests: I am a machine learning researcher specializing in deep learning and computer vision. Broadly, my goal is to understand how we should combine AI and human experts to empower science. My work addresses questions like:

  • How can machine learning make scientific research faster and cheaper?
  • How should machine learning systems incorporate domain knowledge and feedback from scientists?
  • How can machine learning make new kinds of scientific inquiry possible?

Previously: I completed my Ph.D. in Computing + Mathematical Sciences at Caltech in 2023, where I was advised by Pietro Perona and supported by an NSF Graduate Research Fellowship and an Explorer Grant from the Resnick Sustainability Institute. I graduated from Duke University in 2017 with a B.S.E. in Electrical and Computer Engineering and Mathematics. I've also spent time at Google Research, Microsoft Research, the Air Force Research Lab, the Duke University Marine Lab, and the Woods Hole Oceanographic Institution. I'm a proud product of public schools in Utah (Grantsville, Sandy, Salt Lake City), Nebraska (Omaha), and Texas (San Antonio).
