View Havovi's profile on ResearchGate
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 postdoctorate, 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.
