Sesquicentennial Distinguished Professor Greg Cook

Research interests:

Microbial physiology and biochemistry, antimicrobial resistance, drug discovery, molecular microbiology, structural biology

Current research:

Research in my laboratory is focused on developing bacterial metabolism and energetics as a new target space for drug development to combat bacterial pathogens (Mycobacterium tuberculosis) and environmental microorganisms that contribute significantly to greenhouse gas emissions. The goal of this research is to produce a new class of antibiotics that specifically target the metabolism of microorganisms in their environment. This research includes bacteriology, biochemistry, protein purification and crystallography, PC3 laboratory experiments, molecular biology and genetics.

 Appointments and Honours:

  • Deputy Director, The Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland.
  • Chair-elect, Gordon Research Conference on Bioenergetics (vice Chair 2019, Chair 2021).
  • University of Otago Research Group Award 2017,Otago Bacterial Energetics and Antimicrobial Resistance Group
  • University of Otago Distinguished Research Medal, 2014 (University of Otago's highest distinction)
  • Fellow of the Royal Society New Zealand Te Apārangi, 2013
  • James Cook Fellow, 2012-2014
  • 8th Sir William Dunn Fellow, 2009 (Cambridge U.K.)

Research projects 

  • A. Bacterial energetics as a new target space for drug development

  • B. Fueling persistence: adaptation of Mycobacterium tuberculosis to hypoxia and low energy conditions

  • C. Antimicrobial resistance and finding new drugs for environmental microorganisms

These projects utilize modern technologies (e.g. proteomics, transcriptomics, molecular biology and structural biology) to address important questions in bacterial adaptation to environment.
