  • Sharon Turban Lab

    Research in the Sharon Turban Lab focuses on the effects of sodium and potassium on blood pressure and on kidney function. We lead the Chronic Kidney Disease-Potassium (CKD-K) clinical trial, funded by American Heart Association, which examines the benefits and safety of two levels of potassium intake in patients with kidney disease. Other research includes the Chronic Renal Insufficiency Cohort (CRIC) study, which aims to improve the understanding of chronic kidney disease and related cardiovascular illness.

    Research Areas: sodium, kidney diseases, potassium, chronic kidney disease, blood pressure

  • Stephen Sozio Lab

    Dr. Sozio’s research focuses on 1) Clinical research related to chronic kidney disease and end stage renal disease, and 2) Educational research in undergraduate and graduate medical education.

    The Sozio lab pursues work related to stroke, cognitive impairment, manifestations of kidney disease, and systematic reviews on clinical topics, and collaborates on multiple projects with other key investigators. In particular, Dr. Sozio has been an active investigator in the Choices for Healthy Outcomes in Caring for ESRD (CHOICE) Study, Predictors of Arrhythmic and Cardiovascular Risk in End Stage Renal Disease (PACE) Study, Chronic Renal Insufficiency Cohort (CRIC) Study, and work funded through the Agency for Healthcare Research and Quality (AHRQ) and Johns Hopkins Evidence-Based Practice Center. In addition, the Sozio lab performs studies at the UME and GME levels, investing in understanding learners’ mentorship, research, and transitional experiences.

    Research Areas: end stage renal disease (ESRD), epidemiology, kidney diseases, stroke

  • Tariq Shafi Lab

    Research in the Tariq Shafi Lab focuses on improving the care of kidney failure patients who are on dialysis. We’re developing methods to evaluate and estimate residual kidney function—a strong predictor of survival in dialysis patients—and identifying ways to halt the loss of residual kidney function. We’re also involved with the Choices for Healthy Outcomes in Caring for ESRD (CHOICE) study, which compares the effectiveness of common treatment strategies for patients with end stage renal disease (ESRD).

    Research Areas: end stage renal disease (ESRD), dialysis, kidney diseases
