The main problems I've worked on are:
- Word segmentation and morphology learning: In the first years of life, children learn to segment the speech stream into structured words. I work on algorithmic-level, online models of acquisition that are computationally efficient, cognitively plausible, and predict the ways in which infants learn over time.
- Morphological processing: I use computational modeling to extend experimental work by evaluating theories of morphological processing using large scale data. My work focuses on the debate surrounding the role of frequency in facilitating processing and the nature of morphological decomposition.
- Natural language understanding for autonomous systems: In situations like search and rescue, we need robots to perform complicated tasks under limited supervision. As a part of the SUBTLE MURI project, I've developed SLURP, a system that allows users to specify simple tasks for a robot to perform using natural language by translating their instructions into a satisfiable logical plan.
I've also done research in more traditional natural language processing. I developed MORSEL, a cognitively-motivated state-of-the-art unsupervised morphological analyzer. From June-August 2012, I participated in the SCALE summer workshop at the Johns Hopkins Center of Excellence in Human Language Technology. With Mitch Marcus, I developed Codeswitchador, a system for identifying code-switching in social media data. This work enables the creation of large scale corpora of code-switching and identification of bilingual users.
I graduated from Yale in 2006 with a B.A. in Computer Science and Psychology. As an undergraduate I performed research in social robotics, working with Brian Scassellati and Emily Wang, and unsupervised language learning, with Charles Yang. I also spent a tremendous amount of time working on the shows and serving on the board of the The Yale Dramat. Between college and grad school, I worked for the Microsoft Auto team on speech recognition and text-to-speech in cars, specifically on Ford Sync and Kia UVO. I also worked with the Microsoft Research Speech Technology Group on CommuteUX.
