I’m a Computing and Mathematical Sciences Ph.D. student in the Computational Vision Group at Caltech, advised by Pietro Perona. I’m also involved in the Visipedia project.

I’m interested in computer vision, machine learning, and using these techniques to enable scientific progress in ecology and medicine. My work is supported by an NSF Graduate Research Fellowship.

I graduated from Duke University in May 2017 with a B.S.E. in Electrical and Computer Engineering and Mathematics. I’ve also spent time at Microsoft Research, the Air Force Research Lab, the Duke University Marine Lab, and the Woods Hole Oceanographic Institution.

Previously, I’ve worked on OCT imaging and image processing with Sina Farsiu, datacenter-level computational sprinting with Benjamin C. Lee, bioacoustic signal detection with Douglas Nowacek, environmental sensing with Martin Brooke, and oceanographic data analysis with Cindy Van Dover.
