Welcome to the webpage of the Boulder Language and Social Technologies research group (BLAST), led by Prof. Maria L. Pacheco.
We are based in the Department of Computer Science at the University of Colorado Boulder.
At BLAST we work on Natural Language Processing, Machine Learning and Computational Social Science. We are broadly interested in finding transparent and replicable insights to societally relevant problems through the computational analysis of language. In general, we are curious about:

BLAST at ACL 2026: Congrats to Rohan (and team: Advait, Alex, Zohar), Alvin (and team: Rohan, Dananjay, Alexandria, Maksim), Obed, and Prajakta (in collaboration with Shira’s team at Amherst) for their papers accepted to ACL 2026. We have work spanning narrative induction, interactive knowledge discovery, logical common sense reasoning and mechanistic interpretability for language artifacts. Looking forward to a great conference!
