Research programs in Dr. Navar's laboratory investigate hormonal and paracrine mechanisms regulating renal hemodynamics, glomerular filtration rate (GFR), and sodium excretion. Intense activity is also focused on the pathophysiology of hypertension and the role of the intrarenal renin angiotensin system (RAS) in altering kidney function to lead to in angiotensin II dependent hypertension
