Faculty Bio

I am an Associate Professor in the College of Health Professions at Pace University in New York City. I earned a PhD in Speech-Language-Hearing Sciences from The Graduate Center, CUNY, in 2012 under the supervision of John L. Locke. My BSc and MSc degrees in Speech and Hearing are from Mangalore University and All India Institute of Speech and Hearing, Karnataka, India.

I enjoy teaching speech, language, and voice science, neuroscience, and research methods -- courses that are inherently interdisciplinary. My teaching is informed by my research, which adopts an evolutionary approach to human behavior. I am especially excited about my new undergraduate course, The Psychology of Language (the equivalent of Psycholinguistics), open to all students at Pace. Currently I am working with a team of professors across disciplines to launch a multidisciplinary badge following the Evolutionary Studies (EvoS) model at SUNY, New Paltz.

Research Interest

I am interested in the human capacity for spoken language, social evaluations based on speech, vocal-verbal flexibility, and cultural diversity.

One of my recent projects used the evolutionary psychology framework to weave together findings from sociolinguistics, speech science, and phonetics to address speech-based social evaluations. This was done in collaboration with two labs: Evolutionary Psychology Lab, SUNY, New Paltz, directed by Glenn Geher, and Behavioral Endocrinology and Evolution Lab, Penn State, University Park, directed by David Puts.

Another project explored the utility of culturally diverse samples and a historical outlook in research on mate choice. Although counterintuitive, the project has implications for research on spoken language. This was a collaboration with Maryanne Fisher, Saint Mary’s University, Nova Scotia.
