Our Fellows

Aaron Hengist.
Aaron Hengist, Ph.D.
Visiting Fellow

My work investigates how manipulating dietary macronutrient composition influences energy balance and metabolic health in humans. We aim to understand the integrated physiology of these responses using a combination of whole-body and mechanistic measures. My current project is investigating how switching to a ketogenic diet impacts sleeping energy expenditure, substrate oxidation, and hepatic metabolism in an inpatient feeding setting. We are also exploring the potential for Nicotinamide Riboside supplementation to augment these effects.

Nicholas Foreman, Ph.D.
Nicholas Foreman, Ph.D.
Postdoctoral Fellow

Nick Foreman is a Postdoctoral Fellow in NIDDK working with Dr. Chung. His research interests focus on lifestyle interventions to improve cardiometabolic health, which he will now use to better understand mechanisms of type 2 diabetes in young adults. He has a Ph.D. in Exercise Physiology and Applied Nutrition from George Washington University, where he studied the acute cardiometabolic effects of high-fat overfeeding with and without exercise. He enjoys running, baking pastries, and cheering on the Minnesota Vikings.

Madilyn Gaydos is a senior post-baccalaureate IRTA fellow on Dr. Stephanie Chung’s team. She graduated with High Honors with a B.S. in Biochemistry and a minor in Science, Technology, and Society from the University of Michigan. Earlier in her fellowship, Madilyn conducted basic research at the National Cancer Institute studying T-cell therapies for solid tumors before transitioning to clinical research focused on cardiovascular risk in youth-onset type 2 diabetes. She coordinates the Young at Heart Study and supports young adults through the team’s endocrinology transition clinic, including patients from underserved populations and those facing barriers to care. Following her fellowship, she plans to attend medical school and pursue a career integrating longitudinal patient care, research, and efforts to address health disparities.

Her interest in nutrition and chronic disease grew from a desire to understand how biological, behavioral, and lifestyle factors influence health. Olivia took an interest in the role of antipsychotics and chronic disease medications and its metabolic effects in college. At NIH, Olivia contributes to clinical research examining nutrition, metabolism, and obesity, including research evaluating photograph-based dietary assessment tools. She is particularly interested in the intersection of nutrition, behavior, and chronic disease and hopes to pursue a career focused on improving patient health through nutrition and patient-centered care.

Study Coordinator/Post-Baccalaureate IRTA Fellow

Elise Hubert is a first-year post-baccalaureate IRTA fellow on Dr. Stephanie Chung’s team.She graduated from Wright State University with a B.S. in Population and Public Health. As an undergraduate, Elise developed an interest in addiction medicine and health disparities through volunteering with a local nonprofit organization serving individuals experiencing homelessness, food insecurity, and addiction. This experience inspired her interest in understanding how social and structural disparities affect health outcomes and chronic disease management. During her fellowship, Elise looks forward to building on these interests by exploring the impact of health disparities on Type 2 Diabetes management. Following her fellowship, she plans to pursue a career as a physician, combining her interests in medicine, public health, and health equity. Outside of the NIH, Elise enjoys watching sports, spending time outdoors, and reading.
