Research interest

Our team aims to identify new hormonal systems, which coordinate insulin sensitivity and energy expenditure across tissues. More specifically we study novel hormones and blood factors mediating the cross talk between liver and adipose tissue in response to feeding cues, such as fasting-refeeding, time restricted feeding and obesigenic diets. Our research aims to increase the understanding of the complex physiology of feeding and energy balance and directly works on the development of new therapeutics factors of Type 2 diabetes and the new diagnostic biomarkers of early diabetes. In hypothesis-driven approaches we perform all steps from the discovery to preclinical testing of novel metabolic factors.

Project

Development of novel hormones-based therapeutics against insulin resistance and Type 2 diabetes

The successful candidate for this project will utilize recombinant protein techniques to design and purify novel therapeutic proteins and peptides, which he/she will test on mouse models of obesity and Type 2 diabetes. In addition, the PhD candidate will employ classical biochemistry, molecular biology and state of the art high throughput methods (proteomics, phoshoproteomics, metabolomics) to identify signaling receptors and novel molecular pathways to understand the function of the studied novel hormones. Finally characterization of mouse models of loss and gain of function, as well as work with adenoviruses and adenoassociated viruses (AAV) will be part of the PhD training. The candidate will work with a young PI, who offers extensive training and mentoring in a highly equipped and multidisciplinary  environment.

Your profil: Masters degree in biology, biochemistry, molecular medicine or related fields. Previous exposure to and experience with basic biochemical and molecular biology techniques is essential.
