Gabriel Chuang

Hi, I'm Gabriel! I'm a third-year PhD student in Computer Science at Columbia University, where I am advised by Augustin Chaintreau and Cliff Stein. I'm a member of the theory group and the Mobile Social Lab.

I am interested in questions that combine one or more of {social networks, fairness, machine learning, and elections}. Other things I think are cool include {computational social science, language models/synthetic data, and redistricting}.

Prior to Columbia, I spent one year as a staff researcher at Duke, working with Jonathan Mattingly and Greg Herschlag on using hierarchical MCMC methods to sample Congressional districting plans. I did my undergrad at CMU, where I got concentrations in Algorithms & Complexity and Robotics and worked with Anupam Gupta on online perfect matchings with deadlines. Before that, I spent a summer at NASA's Ames Research Center and a few semesters working in the Biorobotics lab at CMU.

Outside of work, I enjoy drawing (I post on instagram), hiking, and playing board games (recent favorites: Ark Nova, Concordia, Wingspan). I am also on the student board of the Columbia Catholic Ministry.

I am supported by the NSF Graduate Research Fellowship.

Teaching

I find great joy in teaching undergrad-level CS to students new to formal mathematics, especially topics that have to do with discrete math, proofs, and Functional Programming. I have TA'd in the following capacities:

• S24: Columbia COMS 4223: Networks, Crowds, and the Web
• S23: Duke MATH 560: Algorithms
• S22, S21, S20: CMU 15-150: Functional Programming
• F21: CMU 15-151: Mathematical Foundations for CS (Head TA)
• F20, F19: CMU 15-151: Mathematical Foundations for CS

I am also one of the PhD Coordinators for the Emerging Scholars Program.
