I am a senior postdoctoral researcher in the Department of Molecular and Experimental Nutritional Medicine at the University of Potsdam, Germany (group of Prof. André Kleinridders). I received my PhD in Molecular Biology from the German Institute of Human Nutrition in 2022, focussing on mitochondrial function in adipose tissue. During that time, I started working on the influence of selenoproteins on adpocyte functions. My current research centres on the interplay of selenium, redox biology and metabolism, with a focus on adipose tissue insulin sensitivity in obesity. A main line of my work addresses the extracellular selenoprotein glutathione peroxidase 3 (GPx3) and its role in regulating insulin receptor expression and adipocyte function, combining cell culture, adipose tissue explants, mouse genetics and human adipose tissue from bariatric surgery. The main goal is to find ways to re-instate insulin sensitivity in metabolic disorders.
