Naomi Caselli is an Assistant Professor of Deaf Education and the co-director of the AI and Education initiative at Boston University. She is hearing, and her first languages are ASL and English. She leads a research team that documents the structure of the American Sign Language lexicon, the effects of language deprivation on language acquisition, and developing AI-enabled sign language technology. She is a co-developer of ASL-LEX, an award-winning lexical database documenting the ASL lexicon, and the ASL-CDI 2.0, an early ASL vocabulary assessment. Her work centers around four themes:

1. How does early language experience shape how deaf children learn language?
2. How is the sign language lexicon is structured?
3. How does the structure of the lexicon affects language acquisition, processing, and evolution?
4. How can computing technology be accessible to sign language users?
