David Wadden

Hi! I'm David Wadden. I'm a final year PhD student in the NLP group at the University of Washington, advised by Hanna Hajishirzi.

I'm on the job market, looking for industry research positions! If you're hiring, feel free to send me an email.

I study Natural Language Processing and Machine Learning, with a focus on applications in science and health. I'm particularly interested in building systems to assist researchers in extracting and verifying findings reported in scientific research.

Before grad school, I spent a few years working in genomics at the Broad Institute. Before that, I studied physics at Amherst College.
