Jeffrey Gleason

Hi! I’m a 5th-year Computer Science PhD candidate at Northeastern’s Khoury College, where I’m advised by Christo Wilson. My work is supported by an NSF Trainee Fellowship: Platforms for Exchange and Allocation of Resources (PEAR). I am currently looking for Trust & Safety data science positions and post-docs.

I am a computational social scientist interested in questions about the governance of online platforms. My work focuses on 1) the economic power of online platforms and 2) trust and safety on online platforms. Methodologically, I’m interested in the design of experiments and observational causal inference. I was a PhD Data Science Intern on Roblox’s Trust and Safety team in summer 2024 and 2025.
