Mary M. Flynn, PhD, RD, LDN is an Associate Professor of Medicine (Clinical) at Brown University and a Sr. Research Scientist at The Miriam Hospital, where she has worked since 1984. She is the outpatient dietitian at TMH for oncology. She taught nutrition at Brown University from 1998 to 2023 and has lectured in the medical school on nutrition topics since 1998. Her main research interest is how food can be used as medicine and her main food of interest is extra virgin olive oil, which she has been researching since 1999. ​

In 1999, Flynn developed a plant-based, olive oil diet that she has since tested for weight loss in women diagnosed with invasive breast cancer; in men with prostate cancer for weight loss and improvement in components of the metabolic syndrome; and to decrease food insecurity in food pantry clients and medical students.
