Faculty

Dr. Roland is a specialist in rhinology and anterior skull base disease, including chronic rhinosinusitis, nasal polyps, fungal sinusitis, nasal obstruction, and CSF leaks.

Electrical and chemical signaling across membranes, neural temporal code, spike generation, molecular anatomy of synapses, membrane excitability disorders, auditory and vestibular systems, synaptic electrophysiology, sensory hair cells, spiral ganglion neurons, ribbon synapses, ion channel organization and function, nano-scale microscopy, Ca2+ and voltage imaging, mutational analysis, computational modeling, cochlear implants, structure-function relationships, synaptic development and heterogeneity, genetics of hearing and deafness, optogenetics, mitochondria, network and synaptic plasticity, efferent neuromodulation of sensory processing, prevention of hearing loss.

Hair cells are the sensory receptors of sound, motion, and spatial orientation. Exposure to excessively loud noise or certain drugs can permanently damage hair cells and their connections to nerve fibers. My lab investigates the cellular mechanisms of noise-induced and chemical hair-cell damage using zebrafish as a model for human hearing and deafness.

Dr. Spataro specializes in rhinoplasties for both functional and cosmetic purposes, facial Mohs reconstructions, facial trauma, cosmetic surgeries and procedures such as Botox, fillers, brow lifts, eyelid surgeries, facelifts/necklifts, laser and chemical peels for skin resurfacing.

Research Interests: Speech perception by hearing-impaired listeners, especially cochlear implant users; perception of talker-specific properties of speech by cochlear implant users, perception of suprasegmental speech characteristics and its relation to learning words; psychoacoustic abilities of cochlear implant users and of persons with unilateral hearing loss.

Research in my lab focuses on the development and regeneration of sensory receptors and afferent neurons in the inner ear.
