Dr. Tasian’s research program focuses on two areas: nephrolithiasis (kidney stone disease) among children and adults, and chronic kidney disease in children with congenital abnormalities of the kidney and urinary tract. 

He spends much of his time investigating the epidemiology of nephrolithiasis, with a particular emphasis on the temperature dependence of kidney stone presentation, environmental determinants of nephrolithiasis, and interventions to decrease the risk of stone recurrence among adolescents and adults. Dr. Tasian is supported by a National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases K23 Career Development award, the goal of which is to identify interventions to increase water intake for the secondary prevention of kidney stones. He is also a PI in the Urinary Stone Disease Research Network. Dr. Tasian also has active studies that are investigating the role of the microbiome in kidney stone disease.

In addition, he has active investigations examining risk factors for chronic kidney disease progression among children with congenital abnormalities of the kidney and urinary tract. This research seeks to identify novel anatomic biomarkers that can be measured using routine renal ultrasonography. The goal is to identify the population of patients who may benefit from early interventions to slow progression of chronic kidney disease.
