I am a Managing Principal Research Scientist at Educational Testing Service in Princeton, New Jersey. My research interests span computer science, education, and linguistics, including natural language processing, automated essay scoring and evaluation, educational technology, discourse and sentiment analysis, education policy, English language learning, and writing research.. The intersection of my interests has led to two of my inventions: E-rater®, an automated essay evaluation application, and Language MuseSM, 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.
I really love building and managing system development from the early idea through product implementation phases. Working with users is one of my favorite aspects of system design. Over the past few years, I have spent a lot of time talking with K-12 teachers. Lately, I spend a lot of time reading about the Common Core State Standards Initiative to inform my thinking about building new systems that support teaching and learning. 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.
