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 hepatic insulin sensitivity and pancreatic β cell function. 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.
