The Language Accessibility Research (LARCH) Lab at the
University of Washington
is a team of faculty and students working on designing, building, and evaluating language technologies that make information more accessible and understandable for everyone.
We study how people search, read, interpret, and act on complex information, then build systems that support those moments with clarity and care.
Our goal is to empower people to discover information and collaborate effectively with AI systems on complex decision-making tasks. We are especially motivated by problems in high-expertise domains such as healthcare and science communication, where information is abundant, decisions are consequential, and language can either open access or create barriers.
Research Areas
Language Accessibility
We study how language technologies can make complex information easier to find, understand, and use across different levels of expertise, literacy, and access.
Health and Clinical AI
We design and evaluate language-based tools for healthcare contexts, with attention to clinical workflows, patient communication, safety, and evidence traceability.
Scientific Evidence and Knowledge
We build methods for extracting, organizing, and synthesizing scientific information so people can reason across large bodies of literature.
Human-AI Collaboration
We investigate how people collaborate with AI systems during search, writing, interpretation, decision-making, and sensemaking tasks.
