Katrina is a Postdoctoral Research Fellow in the Islet Biology lab, headed by Professor David Hodson, at the Institute of Metabolism and Systems Research. Her research focuses on investigating the function of vitamin D binding protein in pancreatic alpha cells.


  • PhD in Anatomy, Pathology and Physiology, Kingston University, 2018
  • MSc in Biotechnology, Kingston University, 2013
  • BSc Biology, University of Alaska Anchorage, 2011


Katrina completed her BSc in Biology at the University of Alaska Anchorage. She later pursued her MSc in Biotechnology at Kingston University London. Katrina continued to complete her PhD at Kingston University with Dr. Natasha Hill. Her research investigated SPARC matricellular protein expression in the pancreas, and how they function in regulating insulin secretion from beta cells.

In 2018 she joined the IMSR at the University of Birmingham for her postdoctoral studies in Professor David Hodson’s Islet Biology Group. Her research interests include studying alpha cell function and glucagon secretion in vitamin D-binding protein-deficient mice.


Vitamin D binding protein (DBP) is highly expressed in glucagon-secreting alpha cells. To investigate DBP function, the research utilises microscopy techniques combined with molecular biology to investigate protein expression and signalling in islet cells. The research also uses tissue from mouse models as well as tissue from individuals with diabetes to investigate DBP function in diseased states.
