Hello and welcome! I am an NLP and health informatics researcher, studying how to design and build language technologies to improve access to and understanding of information, especially in high-expertise domains like science and healthcare. My work has resulted in techniques and tools to improve access to scholarly content, synthesize scientific evidence, and support people to make better decisions about their health.

I am an Assistant Professor at the University of Washington Information School, where I lead the Language Accessibility Research (LARCH) lab. You can find a list of our publications here.

news

12/20	Our paper “Explainable AI for Clinical Outcome Prediction: A Survey of Clinician Perceptions and Preferences” led by lab alum Jun Hou, has been accepted to AMIA Informatics Summit!
11/05	I received a Google Academic Research Award for “AI-Driven Accessibility Solutions for STEM Educational Materials: Bridging Accessibility Gaps for Blind and Visually Impaired Students”!
10/16	New preprint: “Varying Shades of Wrong: Aligning LLMs with Wrong Answers Only” showing the benefits of preference alignment between wrong answers only.
10/03	Two 🌴EMNLP🌴 paper acceptances! “APPLS: Evaluating Evaluation Metrics for Plain Language Summarization” to the main conference and “Characterizing LLM Abstention Behavior in Science QA with Context Perturbations” to Findings.
08/31	Very excited to have been awarded an NIH R01 led by PIs Lynn Worobey and Heather Feldner! We will have an opportunity over the next five years to study experiences of ableism for people with mobility disabilities and impacts on their health outcomes using mixed methods approaches.
