Before joining Google as a research scientist in May, 2013, I was a faculty member for 9 years in the Center for Spoken Language Understanding (CSLU) at the Oregon Health & Science University (OHSU) – part of what used to be the Oregon Graduate Institute (OGI).  Before that, I was in the Speech Algorithms Department at AT&T Labs - Research from 2001 – 2004. I finished my Ph.D. in the Department of Cognitive and Linguistic Sciences at Brown University in 2001. There I was part of the Brown Laboratory for Linguistic Information Processing.

I am a computational linguist working on various topics in natural language processing. My research interests include: language modeling for automatic speech recognition, text entry and other applications; weighted transducers and grammars; supervised and unsupervised learning of language models; text normalization and transliteration; pronunciation modeling; text entry, accessibility and augmentative and alternative communication (AAC); syntactic parsing of text and speech; statistical models of human language processing; spoken language processing for diagnosis of neurodevelopmental and neurodegenerative disorders.

Some recent-ish activities, links and/or resources:

• I am co-organizing (w/Kyle Gorman and Richard Sproat) the First ACL Workshop on Computation and Written Language (CAWL), to be held at ACL 2023 in Toronto, July 2023.
• I was co-Editor-in-chief for the Transactions of the Association for Computational Linguistics (TACL) from 2018-2022. The journal's 2021 impact factor was the topic of an MIT Press blog post.
• Here's the site of the Dakshina dataset, an open-source collection of romanized and native script Wikipedia in 12 South Asian languages that I helped put together.
• Here's a 2021 Google Research blog post about some work my team was involved in, transliterating geo entity names into Brahmic scripts. And here's an earlier (2017) post about some related work I contributed to, providing transliteration keyboards in 20+ South Asian languages.
