Aaron Clark, MD, PhD
Associate Professor
Neurological Surgery
School of Medicine

Clark earned his medical and postdoctoral degrees from Virginia Commonwealth University. He completed his neurosurgery residency at UCSF, where he developed his interest in spine surgery and began publishing research on spinal oncology, spine biomechanics, spinal deformities and neurophysiological monitoring during spine surgery. In 2014, he completed a fellowship in minimally invasive spine surgery at the Semmes Murphey Neurologic and Spine Institute in Memphis, Tennessee, under the mentorship of Dr. Kevin Foley, a pioneer of minimally invasive spine surgery.
