jbragg [at]

I am a fifth-year Ph.D. student in Computer Science & Engineering at the University of Washington, advised by Dan Weld and Mausam. My primary research interests are in artificial intelligence, machine learning, and human-computer interaction. In particular, I am interested in making crowdsourcing more broadly useful by reducing the effort required to design and deploy crowdsourcing systems.

Before coming to UW, I completed my undergraduate degree at Harvard College in 2010, and also received a Master's in oboe performance from New England Conservatory through their dual degree program with Harvard.
