Lucy Mailing, PhD received her Bachelor’s in Biology from Kalamazoo College and her PhD in Nutritional Sciences from the University of Illinois, where her dissertation research focused on the effects of diet and exercise on the gut microbiome in states of health and disease.
Lucy is the founder and sole author of lucymailing.com, a site dedicated to evidence-based articles about the microbiome, gut and skin health, and nutrition. She is regularly invited to speak on gut health around the country and has been recognized as one of the most trusted experts in the integrative health space. Lucy plans to continue her academic training and begin a postdoc in 2020 after a gap year dedicated to writing and other projects.
