Dr Peter Santa Maria is a surgeon scientist born and raised in Perth, Australia with a subspecialty interest in Otology, Neurotology and Skull Base Surgery. He specializes in disorders affecting hearing, balance and the facial nerve. His clinical practice and research is committed to findings cures for hearing loss. His lab discovered a way to regenerate the tympanic membrane that is now in clinical trials. His lab is changing how we understand chronic ear infections and is actively developing therapeutics that target infections in the ear and evaluating existing treatments for use in the clinic. Along with his role as Associate Director of SPARK's therapeutic translational program, he co-leads the Otoinnovation Lab and is Chair of the American Academy of Otolaryngology's Medical Device and Drugs Committee. Through these roles he's committed to finding better treatments for patients.

He attended medical school at The University of Western Australia before undertaking his residency in Otolaryngology, Head and Neck Surgery. He was the Neurotology and Skull Base Surgery fellow at Sir Charles Gairdner Hospital (2012), Western Australia before undertaking a three year instructorship at Stanford University in Otology, Neurotology and Skull Base Surgery (2015). He joined Stanford faculty in 2017.

Clinically, Dr Santa Maria specializes in adult and pediatric surgery for hearing, balance and facial nerve disorders. He has a special interest in the management of cholesteatoma, chronic otitis media, ear drum perforations and hearing reconstruction, otosclerosis and stapes surgery, eustachian tube surgery, tumors of the ear and skull base including acoustic neuroma, schwannoma, meningioma, glomus tumors, cholesterol granuloma and squamous cell cancer of the ear as well as hearing implants, including cochlear implants, bone anchored hearing aids. Dr Santa Maria has authored book chapters and published papers particularly focusing on hearing preservation in cochlear implant surgery, surgical and non surgical treatments of ear tumors including vestibular schwannomas (acoustic neuromas) and novel management of difficult to treat chronic ear infections.

Scientifically, Dr Santa Maria completed his PhD in the molecular biology of wound healing of the tympanic membrane at The University of Western Australia (2012). His research includes a novel treatment for chronic ear drum perforations was accelerated through the SPARK program at Stanford, winning the "Excellence in Stanford SPARK 2014" award, and then partnered with Auration Biotech and Astellas pharmaceuticals, to bring the non-surgical treatment for ear drum repair into human clinical trials in 2020. He research now expands to include novel treatments for difficult to manage ear infections and oral wound healing.

Dr Santa Maria co-invented a medical device which won the "Robert Howard Next Step Award in Medical Technology Innovation 2014", as part of Stanford's Biodesign program, that could keep patients warm during surgery. He is actively part of device research teams testing new devices that can monitor dizzy attacks in the home, non invasive ways to treat otitis media with effusion and ways to restore hearing without implanting the inner ear.
