Kate Xu

I'm Kate, an incoming PhD student in Computer and Information Science at the University of Pennsylvania. My research interests are in computer vision and machine learning, including egocentric vision, image segmentation and synthesis, and model interpretability.

Currently, I am pursuing my master's degree in computer science at MIT with Professor John Fernández and Dr. Norhan Bayomi at the Environmental Solutions Initiative. My project utilizes vision transformers to map extreme heat risk in urban areas. In between my master's program, I explored sequential learning and model interpretability as a software engineer intern on the Open Catalyst Project team at Meta AI.

I completed my bachelor's degree in computer science with a minor in mathematics at MIT. As an Undergraduate Research and Innovation Scholar, I leveraged image segmentation to identify viable livers for transplant with Katherine Fairchild at the MIT Quest for Intelligence and Siavash Raigani, MD and Leigh Anne Dageforde, MD, MPH at the MGH.

In addition, I examined the biases of generative models using chest X-ray images with Professor Phillip Isola and Dr. Swami Sankaranarayanan, and I developed a graph database for cyber threat hunting with Dr. Una-May O'Reilly and Dr. Erik Hemberg at MIT CSAIL.
