Senior Research Scientist

jbragg [at] allenai.org


I am a Senior Research Scientist at the Allen Institute for AI (AI2) on the Semantic Scholar Research team.

My research is in AI and Human-Computer Interaction (HCI). I design, build, and study systems that support knowledge work, such as helping people train and evaluate AI models, or helping scientists discover and read scientific literature. These systems often introduce new AI techniques, or apply existing techniques in new ways. Some of these systems focus on improving access for people with disabilities, such as blind and low-vision readers. My work is interdisciplinary, and I publish in both AI and HCI venues on topics including human-in-the-loop machine learning, reinforcement learning, natural language processing, crowdsourcing, intelligent user interfaces, recommender systems, data mining, social computing, and accessibility.

Previously, I was in the computer science departments at Stanford (postdoc), University of Washington (Ph.D.), and Harvard College (A.B.). I am also a musician with degrees from New England Conservatory (M.M.) and Harvard College (A.B.).

If you are interested in working with me, please apply to open positions on my team and/or reach out to me directly.
