Irina Castellanos, PhD

Assistant Professor of Otolaryngology - Head & Neck Surgery

FH 400
Indianapolis, IN


My passion for research stems from my interest in understanding the dynamic interplay between early sensory input, neurocognitive development and functioning, and the social environment across infancy through adulthood. My graduate training, which was funded by an NIGMS R25 award, focused on multisensory processing and allowed me to pursue several research questions concerning how infants and young adults process social linguistic information in the context of audiovisual vs. visual-only stimulation. I then extended this line of research during my postdoctoral training by examining how neurocognitive systems are impacted by a period of early auditory deprivation in pediatric cochlear implant users. My postdoctoral fellowship, which was funded by an NIDCD T32 award and an NCATS TL1 award, provided me with specialized training across several fields, including Otology, Cognitive Hearing Science, and Pediatric Clinical Psychology.

Dr. Castellanos currently serves as the Director of the DeVault Otologic Research Laboratory.

Dr. Castellanos’ research interests center on neurocognitive and social-cognitive development and functioning across the lifespan in individuals with and without hearing loss. She maintains three areas of focused research: (1) social, emotional, and behavioral adjustment following hearing loss, (2) the psychology and physiology of stress and coping, and (3) how early language learning may result from the multisensory coordination of attention during parent-child interactions.
