Projects with a clear spine: how social meaning is inferred.

Theory of Mind

Theory of Mind + deception

A ToM-driven error taxonomy for deception detection

NYU Psychology - AAAL 2026 individual oral presentation

Builds a Theory-of-Mind framework for deceptive communication as failures of mental-state inference, using courtroom testimony and online interaction data to connect intentions, beliefs, reasoning errors, and linguistic cues.

Social media language

NLP + mental health

Emotion dynamics and depression risk on social media

Accepted poster, CogSci 2026

Leads a temporally grounded NLP project on Reddit language, extracting LIWC, VADER, and transformer features to model emotional volatility, agency shifts, and affective change before depression self-disclosure.

Affective decision-making

Health behavior + machine learning

Online health decision-making from YouTube exposure

Manuscript under review

Uses logistic regression and stacking ensemble models on survey data from 608 young adults to predict safe-sex behavioral intentions from digital health exposure, misconceptions, demographics, and psychometric variables.

Human-AI social reasoning

Human-AI interaction

AI and human art perception

IRB-approved study - accepted poster, CogSci 2026

Designs and analyzes an IRB-approved study of how AI versus human creator labels shape perceived creativity, aesthetic value, artistic intent, and social evaluation.

Human-AI social reasoning

LLMs + social decision-making

Prosocial behavior in large language models

NYU Psychology

Leads a collaborative study comparing human and LLM helping behavior in a dynamic cooperative decision-making paradigm across partner policies and environmental contexts.

Mental state inference

Culture + benchmark validity

Cultural bias in ToM evaluations in LLMs

Manuscript in progress

Builds a quantitative coding scheme for Theory-of-Mind benchmark evaluation across GPT-4 and DeepSeek with psychological and cultural frameworks.

Computational social cognition

Memory + cognition

VLTM activation and visual working memory capacity

NYU MA Psychology Research Conference 2025

Designs delayed change-detection experiments to test how activated long-term memory affects visual working memory capacity, analyzing K-values and reaction time with SPSS and JASP.

Affective decision-making

Meta-analysis + environmental psychology

Psychological drivers of pro-environmental behavior

Dali University degree thesis

Conducted an umbrella meta-analysis of 42 studies under PRISMA guidelines, coding effect sizes and synthesizing psychological predictors of environmental behavior.
