My research aims to define mechanisms mediating energy-sensing by the master metabolic regulator AMP-activated protein kinase (AMPK), a key regulator of cellular and systemic energy homeostasis. The metabolic dimensions of diseases including type 2 diabetes, obesity, cardiovascular disease and cancer, have encouraged efforts to develop direct activating drugs for AMPK. Co-ordinating biochemical, crystallographic, mass spectrometry and cell-based projects running in the Kemp group, my research has provided significant breakthroughs in understanding the complex regulatory mechanisms that enable AMPK to perform its critical roles. These findings form the foundations to strategies aimed at developing novel therapeutics to treat diseases that impose enormous medical and economical burdens.
