Welcome to the Natural Language Processing group, PortNLP, at Portland State University!
Our research focuses on advancing natural language processing and large language models.
We study how LLMs generalize across languages, mitigate biases, and improve robustness.
We aim to develop responsible and human-centered AI solutions through active collaborations with researchers in linguistics and social sciences.
In addition to our work at PortNLP, we are also affiliated with the Coco Lab,
a sister research group focused on the intersection of computer science, management, and anthropology.
You can check out our projects and code at
