Background
Associate Professor of Computer Science at Dartmouth College
Leads the Minds, Machines and Society research group
Research focuses on natural language processing (NLP) and machine learning
Aims to understand and mitigate anti-social tendencies in large language models (LLMs), such as stereotypes, toxicity, and misalignment with human values
Develops interpretability methods to demystify the 'black box' nature of LLMs
Explores reinforcement learning for guiding pre-trained LLMs and grounding them via simulations
Builds computational tools using LLMs and classical NLP to study social phenomena like political polarization, bias, propaganda, rumors, and hate speech (computational social science)
Recently expanded research to visual-language models for richer cognitive modeling
Applies LLMs to health and bioinformatics, drawing parallels between genomic sequences and language
