My research investigates questions about perception and language processing, and our group
studies these processes using a combination of computational, cognitive neuroscience, and behavioral techniques. I teach graduate
and undergraduate courses in psychology, neuroscience, and cognitive science, including a laboratory course on speech perception
for non-science majors.

Research
My research focuses on questions about speech and language processing:
How do human listeners recognize speech accurately despite variability
in the acoustic signal?
How does this ability emerge over development, and how malleable is it in adulthood?
How can we develop speech-based tests to measure hearing difficulty using behavioral
and/or neural responses?
To answer these questions, we use techniques that allow us to study spoken word recognition as it happens. These include cognitive neuroscience methods that capture early perceptual processes and eye-tracking approaches that measure lexical activation as the speech signal unfolds. We use these data to inform computational models of speech perception that address questions about unsupervised statistical learning and speech development.

Current Villanova undergraduate? Our lab is always looking for good Psychology and Cognitive & Behavioral Neuroscience majors (and other majors!) who want to learn more about perception and language. Click here to find out more about undergraduate research positions in the lab.
Courses
I teach undergraduate and graduate courses in the Psychology, CBN, and Cognitive Science programs at Villanova. I also teach a Mendel Science
Experience (MSE) course in the College of Liberal Arts and Sciences called
Sounds of Human Language. The course provides non-science majors with a
background in the techniques and approaches used in the natural sciences. We
study this through the lens of spoken language, exploring the acoustic
properties of speech sounds and the mechanisms underlying speech
perception.
