Tejbeer Kaur, PhD

Instructor, Otolaryngology - Head and Neck Surgery

My research goal is to establish a deep understanding of the nature and function of neuron-immune interactions along the auditory pathway during development and disease and understand the contributions of immune system towards neurodegeneration, protection and regeneration in deafened ears. I am currently investigating the influence of macrophages (innate-immune cells) on neuronal, axonal and synaptic pathology in animal models of human sensorineural hearing loss. In parallel, I am studying to understand the role of cochlear resident macrophages during development, maturation and homeostasis.
