About Dr. Ian M. Purcell
Ian MacKinnon Purcell was born in San Francisco, California on January 4, 1963, the son of Elizabeth Stuart Rubey and Albert Purcell. After completing his work at Texas City high school, Texas City, Texas, in 1981, he attended Southwestern University, Georgetown, Texas. He received the degree of Bachelor of Science in Chemistry in May 1985. He worked in residential building and electrical contracting in the state of Texas and subsequently enrolled in the Neuroscience Graduate Program as an extended student at the University of California, San Diego from August 1987 to May 1989. In September 1989 he enrolled in the combined M.D. / Ph.D. program in Neuroscience at the University of Texas Medical Branch, Galveston. In September 1990 he entered the Vestibular Neurophysiology Laboratory of Adrian A. Perachio, Ph.D. where he completed 11 years of vestibular and aerospace training. He also received six years of funding from the NASA Graduate Training Grant and The Texas Space Grant Consortium as a principal investigator. As a neurophysiologist, aviator, and Russian jet war bird enthusiast, he is very interested in providing insight as to how sensory information related to gravity is encoded and processed by the vestibular system to control oculomotor and postural reflexes as well as spatial orientation of the human body moving through a complex three-dimensional environment.
Dr. Purcell is a world renowned vestibular specialist and currently lectures and instrcuts at large ENT and Neurology hospitals throughout the US, Asia, and Middle East. His current Oto-Neurology practice focuses on complex vertigo and balance disorders. He has a passionate interest in providing insight as to how sensory information related to gravity is encoded and processed by the vestibular system to control oculomotor and postural reflexes as well as spatial orientation of the human body moving through a complex three-dimensional environment.
Dr. Purcell is also a co-founder of , whose focus is to create innovative products that allow patient access to better diagnostic and treatment strategies to the variety of vestibular and balance disorders that render an individual dysfunctional and unable to perform activities of daily living. These include portable eye movement devices that can be worn like a pair of ski goggles that allow patients to record their eye movements during episodes of vertigo or disequilibrium. These episodes typically occur randomly throughout any given day of the patient's life. Often a patient may present to their physician's office when they are experiencing disequilibrium or frank vertigo, but more often than not these transient epidsodes occur when the patient is away form the physician's office. By the time the patient can obtain a follow-up visit with their physician, the episode has self-resolved, and it is often unclear as to what the etiology of the patient's symptoms were at that time. has worked diligently over the last several years to design a series of products that can not only be used in a physician's office, but also by the patient at home to obtain objective data evidence via eye movement recordings that may allow a better diagnostic and treatment strategy for the patient. Some of the devices designed can not only be used in an acute office setting, but also by a physician in settings that may resemble an emergency room or acute care clinic.
