Greg Cook，Professor of University of Otago, Dunedin, New Zealand. His current research is aimed at gaining mechanistic insight into how bacteria sense and respond to their environment at the level of the cytoplasmic membrane. The membrane proteins and signaling pathways involved and how they control the physiological response of a particular bacterium to environmental signals is a major focus.Current research projects:Adaptation of the membrane-bound F1Fo ATP synthase to function under different environments；Energetics of Mycobacterium tuberculosis: adaptation to hypoxia and low energy conditions Bacterial sensing of antimicrobial stress.
