Research Interests

As the prevalence of metabolic disorders such as obesity and type 2 Diabetes is constantly rising, our main research interest is on the regulation of human energy balance. All our research is done in a clinical experimental setting in healthy participants and patients within the Metabolic Core Unit (MCU) of the CBBM. A special focus of our work is on

  • homeostatic vs. hedonic control of hunger/appetite and food intake
  • regulation of glucose homoeostasis
  • physical activity, exercise and energy expenditure
  • neurocognitive impact of food
  • metabolic consequences of brown adipose tissue activity
  • chronobiological rhythms in the context of human energy balance

We use a broad spectrum of techniques comprising comprehensive hormone analysis, neurocognitive and behavioral testing, food analysis, gold-standard glucose clamp techniques, indirect calorimetry for the assessment of energy expenditure, air displacement plethysmography (BOD POD®) and dual energy X-ray absorptiometry (DEXA) for precise body composition measurement, and accelerometry and continuous heart rate monitoring for the assessment of physical activity under free-living conditions.

We finally seek to identify homeostatic, behavioral and endogenous mechanism impacting on humans´ metabolic health and energy expenditure. Our findings provide deeper insights into mechanisms promoting obesity and related metabolic disorders and may help to develop novel therapeutic strategies.
