Research Interests

Falkenhain works under the mentorship of Drs. Leanne Redman and Eric Ravussin. Her research focuses on cross-disciplinary investigations into human (patho)physiology, particularly how nutritional exposures (e.g., diets varying in macronutrients, signaling molecules such as ketones) affect cardiometabolic health (including glycemic control and energy expenditure). She uses her training in both basic and clinical science to understand individual responses to these interventions, and to link clinical outcomes to underlying mechanisms. In addition, a core pillar of her research program is the development and application of robust analytical frameworks for clinical trials.
