My research focus is on obesity, malnutrition and cardiovascular disease in CKD and dialysis patients. I conduct epidemiological studies of large national databases, smaller but more detailed observational studies, translational studies as well as clinical trials to address questions in the areas of my research interest.

I currently serve as the co-director of the NHLBI Systolic Pressure Intervention Trial (SPRINT) Utah Clinical Center Network and the PI of the SPRINT Utah clinical site. I was a member of the KDOQI Hemodialysis Cardiovascular Guidelines Committee and had the honor of serving on several NIH review panels, NKF and ASN committees.

My team consists of statisticians, study coordinators, clinical study assistants as well as graduate and doctoral research assistants. My mentees have been successful in obtaining meritorious national career development awards and fellowship grants.
