Hadleigh Schwartz’s Homepage

I'm a PhD student in Computer Science at Columbia University, advised by Xia Zhou, Dan Rubenstein, and Vishal Misra. I am broadly interested in computer vision, mobile systems, and security. Currently, my research aims to develop proactive technical solutions to combat deepfakes. I'm a recipient of a Columbia SEAS Presidential Distinguished Fellowship and a Amazon CAIT PhD Fellowship.

Previously, I completed my Bachelor's and Master's in Computer Science at the University of Chicago, advised by Heather Zheng at the SAND Lab.

Teaching/Service

I care deeply about teaching. In addition to serving as a TA for CSEE 4119 (Computer Networks), I participate in Columbia's Teaching Development Program, a multi-year evidence-based teaching certification by the Center for Teaching and Learning, aiding PhD students in refining their pedagogical practices.

Alongside Sam Deng, I co-coordinate Columbia's Emerging Scholars Program, a peer-taught course for first and second-year students aiming to enrich their experience in introductory-level CS courses and provide exposure to the breadth of the field. Unlike typical, programming-focused intro CS courses, ESP is discussion-based and centers on group problem-solving in various CS topics, from NLP to cryptography.
