Dr. Weigand joined NINDS in 2013. She earned her Ph.D. in Physiology from the Johns Hopkins University Bloomberg School of Public Health with support from an NRSA predoctoral fellowship, and received postdoctoral training at the George Washington University in the Department of Pharmacology and Physiology with diversity supplement support.

Dr. Weigand’s research interests have been have ranged from pulmonary physiology and pharmacology to neuro-immune interactions in the lungs to CNS control of heart rate. She undertook studies examining the role of calcium signaling in hypoxic pulmonary vasoconstriction in COPD. Other work focused on understanding the role the peripheral autonomic and sensory nerves in allergic airway disease. In studies related to sleep apnea and SIDS, she conducted research on the recruitment of serotonergic responses in cardiac vagal neurons in the brainstem during hypoxia and hypercapnia.
