Steven Mesquiti

PhD Student | Department of Psychology | Princeton University

My name is Steven Mesquiti! I’m a second-year PhD Student in the Department of Psychology at Princeton University advised by Erik Nook.

Broadly, I am interested in leveraging natural language processing and artificial intelligence to understand and improve mental health outcomes.

The overarching goal of my research is to develop theoretically-informed, language-based tools that can identify individuals struggling with mental health challenges, predict treatment outcomes, and ensure equitable assessment across diverse populations.

I am particularly interested in examining how the semantic content and structure of language—in everyday communication, social media discourse, and therapeutic conversations—can serve as real-time indices of psychological well-being and distress.

To achieve these goals, my research combines advanced natural language processing techniques, machine learning and computational methods, large-scale text analysis, and psychological theory to extract meaningful insights from language data.

Before Princeton, I worked as a Lab Manager for Emily Falk in the Communication Neuroscience Lab at the University of Pennsylvania. Along the way, I have worked with excessively generous scientists like Jamie Pennebaker to answer questions at the nexus of Computer Science, Computational Linguistics, and Psychology.
