Background

In 2011, Havovi earned her doctorate in physiology from University College London, which focused on studying the role of renal and small intestinal glucose transport across the epithelium in metabolic syndrome and diabetes.

As a Postdoctoral Fellow at Brown University, Havovi's research developed into vascular dysfunction in settings of disease including respiratory disease. During her Post-Doctorate, she was awarded significant funding from the American Heart Association, published several peer-reviewed articles and participated in numerous clinical and basic research conference presentations (including invited and peer-reviewed oral presentations) on renal glucose transport, endocytosis, vascular function and respiratory disease.

Currently, Havovi is continuing her research on mechanisms which regulate endothelial and epithelial barrier function, with an emphasis on novel regulators of both barriers, such as the taste receptor.

Research interests
  • Physiological roles of bitter and sweet taste receptors
  • Renal and small intestinal glucose transport across the epithelium (diabetes, metabolic syndrome)
  • Mechanisms regulated by artificial sweeteners and sweet taste receptors (diabetes, pulmonary diseases)
  • Endosomal trafficking in the vasculature (pulmonary diseases)
  • Protein phosphatase (PTP and SHP2) signalling (pulmonary diseases)
  • Protein kinases (PKC and MAPK) signalling (diabetes, pulmonary diseases)
  • Novel mechanisms regulating microvascular complications (diabetes, pulmonary diseases)
  • Molecular mechanisms which link the gut microbiota and gastric permeability
