Research interests span auditory neuroscience, stroke pathology, and regenerative medicine. Key themes include electrical resonance in hair cells via ion channel interactions, Prestin's role in cochlear amplification, Id2-mediated regeneration in auditory epithelium, and cholinergic synaptic function. His lab explores molecular scaffolding proteins and cyclic AMP pathways in cellular regeneration.
Recent publications cover high-frequency prestin dynamics, clot composition in stroke etiology, single-cell transcriptomics for inner ear regeneration, and clinical imaging strategies for dizziness. Articles integrate biophysical, molecular, and clinical approaches across neuroscience and neurology disciplines.
Dr. Navaratnam contributes to Yale's Stroke Center clinical trials using single-cell RNA sequencing and serves as course director for neuroscience education. His clinical practice at Yale New Haven Hospital includes Hearing & Balance Center and 24/7 stroke service.
