Lyndsay Harshman, portrait

Lyndsay Harshman, MD, MS
Assistant Professor of Pediatrics - Nephrology, Dialysis and Transplantation
Lyndsay Harshman completed her pediatric nephrology fellowship at the University of Iowa in 2016 and continued her research in the long-term neurocognitive effects of chronic kidney disease. Specifically, her current work includes an NIDDK funded K23 utilizing magnetic resonance imaging (MRI) to quantitatively characterize the structure of the brain (e.g., volumes of regions and tissues) in mild to moderate pediatric CKD. In conjunction with standardized neurocognitive testing, specialized neuroimaging measures are used to evaluate brain structure, function, and metabolism in this population in order to better understand the relationship to underlying renal disease. Dr. Harshman’s clinical interests focus on aligning the above research concepts of brain growth and development in a chronic kidney disease life-course – specifically in the pediatric renal transplantation population. Her other clinical interests include tuberous sclerosis complex (TSC) patients, for whom she co-founded a multidisciplinary clinic. She is the local PI for the Chronic Kidney Disease in Childhood multicenter prospective cohort study and for the Improving Renal Outcomes Collaborative (IROC), a multicenter quality improvement collaborative focused on improving health, longevity, and quality of life in pediatric kidney transplant recipients.  Dr. Harshman is also the medical director of pediatric kidney transplant at the University of Iowa.
