I am a principal research scientist in Oracle Labs East, which is based in Burlington, MA. I’m currently focused on building machine learning models that help developers find and fix software issues more efficiently. More broadly, I am interested in studying how computational tools–especially those that are powered by machine learning–can be used safely, and to promote social good.

Before Oracle, I completed a Ph.D. at UMass Amherst under the supervision of Andrew McCallum. I received a B.S. in Computer Science from Tufts University and worked as a researcher at MIT Lincoln Laboratory building intelligent decision support systems. I spent the summers of 2014 and 2016 interning at Google.

For a complete list of my publications, see Google Scholar.
