My Bio Research Code Discourse Service

I am currently a Staff Research Scientist at Duolingo, working on the Duolingo English Test. In the past, I was a Distinguished AI Engineer at the ETS AI Labs. I obtained my Ph.D. from the Department of Computer Science at University of Maryland, College Park. I was also a graduate research assistant in the Computational Linguistics and Information Processing Laboratory at the Institute for Advanced Computer Studies, where I worked with my advisor, Bonnie Dorr.

In general, my research has been focused on building systems—with underlying computational models of language—that process written text so as to enhance our experience with those texts. As an example, in my dissertation, I demonstrated the existence of a concrete symbiotic semantic relationship between systems that translate text and those that paraphrase text; I then exploited this relationship to build better translation and paraphrasing systems. Besides machine translation and paraphrase generation, I have also worked on automatic summarization and information retrieval systems. I am also particularly interested in information and data visualization and over the last few years, I have worked on some interesting projects such as visualizing poetry for humanity scholars and interactive scoring for statistical machine translation systems.

My work has allowed to me to apply NLP techniques to build useful educational applications and technologies. Some examples include mining Wikipedia revision history to correct grammatical errors, using paraphrase generation to improve sentiment analysis of essay data, and automatically detecting organizational elements in argumentative discourse.

I also currently serve as the Chief Information Officer for the Association for Computational Linguistics (ACL) with the goal of transforming its current IT infrastructure into a more modern, efficient, robust, and collaborative version of itself.

I have also had a great time teaching computer science during my days as a graduate student and I am hoping to be involved with more of that in the future.
