Dr. Rebecca “Becca” Solch is a Postdoctoral Fellow in the Department of Neurology at Tulane University School of Medicine. She obtained her Ph.D. in Nutritional Sciences from the University of Florida where her dissertation focused on evaluating probiotics on stress-associated gastrointestinal and immune function in undergraduate university students.
