I’m an Assistant Professor at the Department of Linguistics and an Affiliated Faculty at the Department of Computer Science at Boston University. I was a Visiting Faculty Researcher at Google DeepMind until very recently. Before that, I was a Faculty Fellow at the Center for Data Science at New York University and a PhD student in the Department of Cognitive Science at Johns Hopkins University, advised by Dr. Paul Smolensky and Dr. Kyle Rawlins. My interests, broadly, are meaning and generalization in human and machine learners. I use computational and experimental linguistic methodologies to explore these areas. Please refer to the Publications section to find out more.

I’m recruiting: please take a look at the “For students” section if you’re interested in working with me!
