Mar 17, 2025 The pre-print of my new paper “Implicit Bias-Like Patterns in Reasoning Models” is now available on ArXiv. We find that reasoning models (i.e., o3-mini) consume substantially more reasoning tokens when processing association-incompatible information compared to association-compatible information. This pattern parallels the delayed response times humans exhibit when processing association-incompatible information in the Implicit Association Test (IAT).
Mar 10, 2025 The pre-print of my new paper “Visual Cues of Gender and Race are Associated with Stereotyping in Vision-Language Models” is now available on ArXiv. We find that gender prototypicality is linked to greater homogeneity of group representations in VLM-generated texts.
Feb 03, 2025 The pre-print of my new paper “Homogeneity Bias as Differential Sampling Uncertainty in Language Models” is now available on ArXiv. We find that that certain Vision-Language Models exhibit significantly more deterministic token sampling patterns when processing marginalized groups compared to dominant groups. This finding suggests a potential mechanism underlying homogeneity bias in language models.
Jan 09, 2025 I published my very first blog post about my research on homogeneity bias in AI. You can find it on my website as a blog entry or you can read it as a LinkedIn Article.
Oct 11, 2024 I received a $1,000 Small Grant from the Center for the Study of Race, Ethnicity & Equity to expand my research on homogeneity bias in Large Language Models. This study will explore a broader range of models and parameter settings to examine when the bias appears in model outputs.
Jul 11, 2024 The pre-print of my new paper “Probability of Differentiation Reveals Brittleness of Homogeneity Bias in Large Language Models” was made available on ArXiv. We find that homogeneity bias in Large Language Models, as measured by probability of differentation, is volatile across situation cues and writing prompts.
Jun 05, 2024 My paper “Large Language Models Portray Socially Subordinate Groups as More Homogeneous, Consistent with a Bias Observed in Humans” has been made available on the ACM Digital Library as part of the Proceedings of the 2024 ACM Conference on Fairness, Accountability, and Transparency.
May 23, 2024 I will be serving as a Reviewer for the ICML 2024 Trustworthy Multi-modal Foundation Models and AI Agents (TiFA) Workshop. This opportunity aligns with my recent interest in examining stereotyping in multimodal language models.
May 14, 2024 I am happy to share that I will be a program committee member of the Socially Responsible Language Modelling Research (SoLaR) Workshop at NeurIPS 2024.
Apr 29, 2024 I am thrilled to announce that I have been awarded a $1,000 travel grant to attend the ACM Conference on Fairness, Accountability, and Transparency (FAccT) in 2024.
Apr 26, 2024 I was accepted to the OpenAI API Researcher Access Program! As part of the program, I will be granted OpenAI API credits to continue my work on homogeneity bias in Large Language Models.
Mar 30, 2024 My submission to ACM FAccT 2024 titled “Large Language Models Portray Socially Subordinate Groups as More Homogeneous, Consistent with a Bias Observed in Humans” was accepted for publication. See you in Rio!
Mar 22, 2024 I completed a review of a manuscript submitted to the Personality and Social Psychology Bulletin (PSPB). This was my first experience reviewing a paper for a social psychology journal.
Feb 08, 2024 I received the Outstanding Research Award at the Society for Personality and Social Psychology (SPSP) 2024 Annual Convention for my submission titled, “Outgroup Homogeneity-like Effect in Large Language Models.”
Dec 29, 2023 My paper, “America’s Racial Framework of Superiority and Americanness Embedded in Natural Language” was formally accepted for publication at PNAS Nexus.
Oct 23, 2023 My paper “The Effect of Group Status on the Variability of Group Representations in LLM-generated Text” was accepted for poster presentation at the Socially Responsible Language Modelling Research (SoLaR) Workshop at NeurIPS 2023.
Oct 06, 2023 I won the 3MT (3 Minute Thesis) Competition at the Global Research Symposium hosted by the McDonnell International Scholars Academy. I was awarded both the First Place Award and the People’s Choice Award of the Digital Transformation Track.
