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) and Program of Computer Science and Engineering (CSE) of 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 20012004. 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: syntactic parsing of text and speech; language modeling for automatic speech recognition and other applications; supervised and unsupervised learning of language and parsing models; text entry, accessibility and augmentative & alternative communication (AAC); probabilistic models of human language processing; and spoken language processing for diagnosis of neurodevelopmental and neurodegenerative disorders.

Here's a Google Research blog post about some recent work I was involved in, to provide transliteration keyboards in 20+ South Asian languages.
