Dr. Abdelhalim Azzi completed his PhD in 2014 under the supervision of Prof. Steven A. Brown at the University of Zurich, Switzerland where he studied the role of epigenetic modifications, i.e., DNA methylation in regulation of circadian behaviour under different light/dark cycles. He then joined the laboratory of Prof. Stéphane Schurmans at the GIGA research center in Belgium as a visiting scientist where he studied the role of phosphoinositide phosphatase SHIP2 in regulation of apoptosis. He then joined the laboratory of Prof. Xu Wu as a research fellow at the Massachusetts General Hospital, Harvard Medical School, USA where he studied the crosstalk between the hippo signaling pathway and circadian clock. He joined IMOL in 2021 as principal investigator.

Laboratory of Lipids and Chronobiology
Our group is interested in understanding the role of phosphoinositide signaling in regulation of circadian metabolic processes. The main aim of our research is to examine how daily spatiotemporal variations in phosphoinositides affect daily carbohydrate and lipid metabolism. We focus currently on two system models, the 5-phosphatase SHIP2 and the phosphatidylinositol 3-kinase isoform γ (PI3K-C2γ).
