James Maylie Ph.D.

    • Professor of Obstetrics and Gynecology School of Medicine
    • Neuroscience Graduate Program School of Medicine

Dr. Maylie received his Ph.D. from UO Medical School (now OHSU) in 1977 in physiology and completed a post-doctoral fellowship with Dr. Martin Morad at University of Pennsylvania. He was an Associate Research Assistant in the Department of Physiology at Yale University for 5 years prior to relocating to OHSU. Dr. Maylie’s lab primary focus is in the field of neurobiology. He was trained in electrophysiology and Ca2+ imaging and has merged these techniques along with molecular techniques to study fundamental issues in neuroscience. With his collaborator, Dr. John Adelman in the Vollum Institute at OHSU, they have taken advantage of the explosion in the field of neurobiology that occurred in the 1980s and 1990s with the ability to clone and heterologously express functional ion channels and develop transgenic mice. Over the years Dr. Maylie’s laboratory has become truly multi-dimensional employing a wide repertoire of techniques to address fundamental issues in neuroscience.
