I am a Machine Learning Research Scientist at Altos Labs in San Diego. My research focuses on machine learning and computer vision, with an emphasis on building machine learning systems that enable novel scientific discoveries. I have collaborated with experts in many domains, including molecular biology, ecology, oceanography, remote sensing, acoustics, power systems, optics, and medicine.

I received a Ph.D. from the Computing and Mathematical Sciences department at Caltech where I was advised by Pietro Perona and supported by an NSF Graduate Research Fellowship. During my Ph.D. I completed internships at Google Research, Microsoft Research, and the U.S. Air Force Research Laboratory. Before that, I received a B.S.E. from Duke University with a double major in electrical engineering and mathematics. I am grateful to my passionate public school teachers in Utah (Grantsville, Sandy, Salt Lake City), Nebraska (Omaha), and Texas (San Antonio).
