ALEJANDRO CUEVAS
I write amusing things every Friday at ->
I’m a Postdoctoral Fellow at Princeton’s Center for Information Technology Policy (CITP), primarily with Manoel Horta Ribeiro. I received my Ph.D. from CMU in Societal Computing working with Prof. Nicolas Christin. In 2024-25, I worked as a research consultant at Microsoft Research with Madeleine Daepp.
My research develops an intervention science for online security. I study underground and social media markets, online vices, misinformation, sexual abuse, and persuasion, including how generative AI changes their scale, accessibility, and infrastructure. Many of these activities take place in underground and fringe communities so I use a gonzo approach to learn how these ecosystems work from the inside, build systems to measure them at scale, and use experiments and causal inference to test what happens when platforms or governments intervene. The goal is to document online harm and determine which interventions work.
Prior to spending my time in the shady corners of the Internet, I worked in a variety of topics within security: vulnerability reproduction, deep learning for binary analyses, anonymous communications, moving target defenses, usable security, and computer security from legal and organizational perspectives. I am a recipient of the Cylab Presidential Fellowship (2022-2023), and the IEEE S&P Distinguished Paper Award (2018).
I obtained my Bachelor of Science from The Pennsylvania State University as a Schreyer Scholar and a member of The Presidential Leadership Academy. I completed my honors thesis under the supervision of Prof. Peng Liu and Prof. Dinghao Wu as a member of the Penn State Cyber Security Lab. In 2023, I was an intern at Microsoft Research’s Plural Technology Collaboratory, mentored by Glen Weyl and Madeleine Daepp.
I am also the co-founder of Redoux, a fragrance brand born in NY. We have been featured in the NY Times, Vogue, WWD, etc. We received the inaugural Glossier Grant in 2021, 2x Architectural Digest Cleverest Awards (2022, 2023), and an Essence Best in Beauty Award 2024.

(Under Review)
We conduct two preregistered experiments (n=2,012) in which participants selected a book to receive from a large eBook catalog using either a traditional search engine or a conversational LLM agent powered by one of five frontier models. In some conditions, an LLM attempted to persuade participants to buy a certain book. LLM-driven persuasion nearly triples the rate at which users select the sponsored product.
