Research Interests

My research investigates mechanisms underlying early stages of speech perception and language development and how these mechanisms operate within a multisensory environment.  I am especially interested in the process of multisensory integration, which is the combination of two or more senses (e.g. vision and audition) to arrive at a unified perception. Currently, my lab is focused on four main lines of research.

The first investigates the extent to which learners utilize facial cues to comprehend speech. Second, I am interested in our ability to learn the properties and regularities of the input (e.g. the tendency for A to come before B), and how this perceptual learning mechanism tracks input from multiple senses simultaneously. The third line of research examines individual differences in multisensory integration abilities and how these differences in the ability to combine senses are related to social/cognitive functioning, genetics, and linguistic background. Supported by grants from the Bucknell-Geisinger Research Initiative, I am working with clinicians and researchers at the nearby Geisinger Autism and Developmental Medicine Institute to investigate clinical determinants and consequences of multisensory integration functioning. Finally, in collaboration with faculty in engineering and pharmacists at Geisinger Health System, my lab utilizes eye tracking technology while viewing drug labels in an effort to reduce medication errors.

Working closely with undergraduates, I have pursued these questions using behavioral, eye-tracking, genetic, and neuroimaging techniques. If you would like to know more or are interested in becoming involved in my research, please visit my lab website or contact me via email.
