Dr. Stefanie Geisler is a board certified Neurologist with subspecialty certification in Neuromuscular Medicine.  She received her MD from the Charite, the Medical School of the Humboldt University in Berlin, Germany.  Her thesis work focused on the subnuclear organization of the habenular complex.  Her subsequent post-doctoral research with Scott Zahm at the Saint Louis University School of Medicine and Roy Wise at NIH/National Institute on Drug Addiction concerned the anatomical, neurochemical and behavioral organization of the mesolimbic dopamine system.  She then completed the residency program in neurology, followed by the neuromuscle fellowship, both at Washington University in Saint Louis. During residency, she joined the laboratory of Aaron DiAntonio (Developmental Biology). There and in collaboration with Jeffrey Milbrandt (Genetics) she developed her current interest in molecular mechanisms in peripheral neuropathies, which she presently continues to investigate in her laboratory in the Department of Neurology at Washington University.
