Research interests

Our main research interest is on the regulation of human energy balance with a special focus of glucose homoeostasis as well as metabolic consequences of brown adipose tissue activity. We also aim to understand underlying mechanisms of homeostatic versus hedonic control of hunger and satiety and consequently food intake. Further, chronobiological rhythms in the context of human energy balance play a major role in our research efforts.

We use a broad spectrum of techniques comprising gold-standard glucose clamp techniques, comprehensive hormone analyses, neurocognitive and behavioral testing, indirect calorimetry for the assessment of energy expenditure, air displacement plethysmography and MRI for precise body composition measurement, and accelerometry for the assessment of physical activity and sleep under free-living conditions.

We finally seek to identify homeostatic, behavioral and endogenous mechanism impacting on humans´ metabolic health and energy expenditure. As the prevalence of metabolic disorders such as obesity and related metabolic disorders is constantly rising, our findings provide deeper insights into mechanisms promoting obesity and may help to develop novel therapeutic strategies.
