His lab is interested in understanding how both the renin angiotensin and prostanoid systems regulate blood pressure by altering blood flow to the kidney. The lab utilizes a combination of physiologic and molecular techniques in genetically modified mice to probe questions about how changes in the micro circulation of the kidney alter sodium excretion. The overarching goal of this research is to identify novel mechanisms to target drug therapy for patients with hypertension.
