Professional background

  • 2006 – 2009, Research Officer, Institute for Molecular Bioscience, Brisbane
  • 2009 – 2013, Research Fellow, School of Pharmacy, University of Nottingham, UK
  • 2013 – 2020, Lecturer then Senior Lecturer, School of Pharmacy, University of Otago

Research interests

The Vernall research group focuses on the development of heterocyclic small molecules, peptidomimetics and fluorescent tools that target receptors in the human body. The motivation for developing new chemical tools is to better understand disease processes and cell signalling by studying targets implicated in various diseases and conditions. We particularly focus on developing new tools to study G protein-coupled receptors, for example adenosine and cannabinoid receptors. Other Vernall group research includes small molecule ligand development for modulating immune responses and new approaches to studying antibiotic resistance.
