Alexander Herman is an Assistant Professor of Psychiatry at the University of Minnesota Medical School and a member of the Medical Discovery Team on Addiction. He obtained his M.D. and Ph.D. in Bioengineering from the University of California, San Francisco as part of the prestigious NIH Medical Scientist Training Program. Prior to that, he studied complex systems at the Santa Fe Institute. He obtained his B.A. in Physics with High Honors from Wesleyan University. Dr. Herman's interests include the neural mechanisms of decision making that are impaired in depression, addiction and parkinson's disease that may be amenable to treatment with neuromodulation. He combines invasive and non-invasive methods including intracranial electrophysiology, direct brain stimulation, magnetoencephalography and transcranial magnetic stimulation.

Dr. David Darrow is an assistant professor at the department of Neurosurgery at the University of Minnesota and is the principal investigator (PI) for the E-STAND clinical trial and Co-PI on the Mood and Cognition study at the University of Minnesota. He received bachelor’s degrees in Physics and Mathematics at Texas A&M University, and then completed medical school at University of Texas Medical Branch, in addition to a master’s degree in public health with a focus on biostatistics. His interest in combining his background in mathematics and engineering with reducing human suffering led him to the University of Minnesota.
