I am an assistant professor in the Stony Brook University Department of Linguistics, affiliated with the Institute for Advanced Computational Science, Department of Computer Science, Institute for AI-Driven Discovery and Innovation, and Natural Language Processing (NLP) group. My primary research revolves around computational approaches to child language acquisition and their broader implications. In particular,

• Algorithmic models of grammar acquisition, especially morphology
• How those processes drive language variation and change
• What insights they provide for low-resource NLP
• What they can tell us about the the intersection of (low-resource) NLP and cognitive science

I am writing a book titled Child Language Acquisition in the Past: A Mechanistic View of Language Change for Edinburgh University Press. It investigates the role that child language acquisition plays in language change. The broad goal is to build a general understanding of language change grounded in an understanding of its mechanisms. Enabled by algorithmic modeling and corpus methods, I draw insights from traditional historical linguistics, the cognitive science of language acquistion, and findings in variationist sociolinguistics.

My other academic interests, a few of which have intersected my research so far, include (alphabetically): Chinese language varieties, computing history, evolutionary theory, formal language theory, general NLP, human geography, Indo-European historical linguistics, Latin language, paleontology and cladistics, Roman history and culture, Semitic languages, Shona language, Singlish and Singaporean English, software engineering, and writing systems.

In 2020, I received my PhD (my dissertation) from the University of Pennsylvania Department of Linguistics, where I worked with Charles Yang and Mitch Marcus. I received a master's degree from the University of Pennsylania Department of Computer and Information Science in 2018. From 2013 through 2015, I was an Associate Scientist in the Speech, Language, and Multimedia group at Raytheon BBN Technologies where I worked on defense and medical-related projects. I interned with Amazon Alexa AI-Natural Language Understanding in summer 2020.

LIN 330: Language Acquisition Monday/Wednesday 3:30-4:50pm.

The official description:
Introduction to the field of language acquisition. Topics include cognitive processes, role of innate ability and environment, developmental stages, individual variation, universal tendencies, interaction of language and cognition, bilingualism, similarities and differences between first- and second-language acquisition, and language disorders..

SBCs: ESI, SBS+, STEM+

LIN 655: Computational Seminar (Computational Approaches to Morphology Acquisition) Monday/Wednesday 11:00am-12:30pm.

The class will define morphology acquisition as a specific learning problem and discuss models of morphology acquisition. The first part of the course will focus on experimental and corpus work which reveal key features of the morphology acquisition process. The second part of the course will survey computational models of morphological learning, both from the child language acquisition and NLP communities.
