Metabolism of bioactive lipids
The Laboratory focuses on the analysis of lipid mediators (eicosanoids, docosanoids, endocannabinoids) using the UPLC-MS/MS method, in particular to identify the source of production of various mediators and their effect on metabolism and immune cells (i.e. adipocytes vs. macrophages). Currently, the lab is exploring new anti-diabetic lipids, fatty acid esters of hydroxy fatty acids and lipid-related metabolic pathways using stable isotopes and LIMeX platform.
We are always interested to hear from prospective (MSc, PhD or postdoc) candidates. Please submit a short personal statement detailing your research interests and qualifications, and a CV by email, RE: "metabolomics".

Projects
White adipose tissue (WAT) is a complex endocrine organ and its low-grade inflammation in obesity contributes to the development of metabolic disorders. In 2014, a class of WAT-born lipid mediators - fatty acid esters of hydroxy fatty acids (FAHFA) was discovered. FAHFAs are endogenous lipids with anti-inflammatory and anti-diabetic properties, including the enhancement of glucose tolerance, and insulin and glucagon-like peptide 1 (GLP-1) secretion while reducing inflammatory responses [1-5].
