I am a Managing Principal Research Scientist at Educational Testing Service in Princeton, New Jersey. My research interests span natural language processing for educational technology, automated essay scoring and evaluation, discourse and sentiment analysis, argumentation mining, education policy, English language learning, and writing research. The intersection of my interests has led to these two inventions: E-rater®, an automated essay evaluation application, and Language Muse, an instructional authoring tool for teachers of English learners. I co-organize this yearly workshop (usually at NAACL or ACL): Innovative Use of NLP for Building Educational Applications (with Joel Tetreault and Claudia Leacock).
Application-wise, my research focus targets designing NLP-centered systems for the service of learning. I have significant experience managing system design from the early idea stages through product implementation . I believe that working with users from the very early stages is critical, and this is also one of my favorite aspects of system design. In this context, I have spent a lot of time collaborating with K-12 instructors and university faculty. I spend a lot of time reading about the Common Core State Standards Initiative and working with university faculty and administration to inform my thinking about building new systems that support writing instruction and assessment. I think that Understanding Language is a great initiative with a great group of people that illustrates the critical role of language in the Common Core Standards, especially with regard to English learners, and addresses important policy issues about equity in education.
I have become increasingly more engaged in automated writing evaluation and writing research, advocating for building capabilities that cover a greater breadth of genres and relevant writing constructs to improve support for writing instruction and assessment.
