Research Interest
Dr. Boyd-Shiwarski’s research interests are potassium homeostasis and ion transport, with a focus on the regulation of the NCC (sodium-chloride cotransporter) by WNK (With-No-Lysine) kinases. WNK kinases are the only known kinases that directly bind chloride and act as regulators of potassium homeostasis. Her recent studies of have focused on the role of a kidney specific isoform of WNK1 in localizing WNK kinases to a protein complex.
Clinical Interest
I am interested in the clinical management of hypertension. Hypertension is the main risk factor for cardiovascular disease and stroke, and has become a global epidemic and the leading cause of death and disability-adjusted life years. Therefore, the prevention and treatment of hypertension is of vital importance. I am also interested in treating patients with inherited disorders that may lead to electrolyte imbalances and hypertension.
