Research/Clinical Activities

My research focuses on speech perception and language acquisition. More specifically, I am interested in how the brain recognizes words from fluent speech, especially in the context of noise, and how this ability changes with development. For a
more complete research statement, please click here.


Recent research has examined infants' ability to recognize their name in the context of noise, how information from one stream of speech can influence the perceptual processing of an alternate stream of speech, the effects of lexical neighbors on children's naming, and the extent of variability in production across and within talkers.

I also recently collaborated on a project with Dr. Nan Bernstein Ratner, funded by the Bamford-Lahey Children's Foundation, to study whether infant perceptual performance relates to later language development. A synopsis of the funded project can be found at the Bamford-Lahey Children's Foundation Grant Page.
