Research Focus

My research focuses on understanding molecular mechanisms involved in signal transduction regulating critical cellular functions such as embryonic development, proliferation, metabolism and response to stress. We particularly investigate the role of intracellular adaptor molecules that integrate signal transduction pathways by assembling molecular complexes involved in regulating pancreatic beta cell function and white adipose tissue biology in physiological and pathological conditions. More recently, we developed a special interest for the role of the adaptor proteins Nck in molecular mechanisms regulating the unfolded protein response in normal physiological conditions and human pathogenesis associated with impaired glucose homeostasis, and insulin production and biological actions. With this focus on better understanding pancreatic beta cell failure during the development of diabetes and fat tissue behaviour during the development of obesity, my group believes that our findings will contribute to the design of new therapeutic avenues to fight these pathological conditions in humans.
