The main interest of my group is the relationship between diet, obesity, and diseases associated with obesity. More specifically, we are investigating the molecular, metabolic, and cellular mechanisms by which increased adiposity is linked to disease, and how these processes are affected by diet.
One major focus lies on obesity-associated adipose tissue inflammation. We are interested in the cell types that infiltrate human adipose tissue, and the relationship of the resulting chronic low-grade inflammation to insulin resistance and glucose intolerance. We conduct human clinical studies to understand the effect of selected dietary factors on chronic low-grade adipose tissue and systemic inflammation.
