Dr. Serena Bagnasco is an associate professor of pathology at the Johns Hopkins University School of Medicine. Her areas of clinical expertise include pathology and transplant pathology. Dr. Bagnasco serves as director of the Hopkins Renal Pathology Service.
Dr. Bagnasco obtained her M.D. degree from the University of Genova in Italy, and spent several years in the Laboratory of Kidney and Electrolyte Metabolism NIH/NHLBI for her post-doctoral training in kidney physiology. She completed a residency in anatomic pathology at Northwestern University in Chicago, and a clinical fellowship in renal pathology at Johns Hopkins.
Her research interests are in the field of renal physiology and pathophysiology. She has studied how renal cells adapt to the environment of the kidney medulla, characterized by high concentration of salt and urea. More recently she has focused on the pathology of renal transplant, and the use of digital pathology in the analysis of kidney biopsies.
Dr. Bagnasco is on the editorial board of several peer reviewed journal including The American Journal of Physiology, is Academic Editor for PlosOne. Dr. Bagnasco has authored more than 50 articles in scientific journals.

Research & Publications
Dr. Bagnasco's research interests are in the field of renal physiology / pathophysiology, and pathology.
She has studied the mechanisms of adaptation of renal cells to the environment of the kidney medulla, characterized by high concentration of salt and urea.
She and her team have defined the genomic organization of the gene that encodes the major renal urea transporters, which are essential for the process of urine concentration in the mammalian kidney. They are currently studying the pathways regulating expression and function of these transporters in the kidney and at extrarenal sites.
She is involved in collaborative studies and has published several articles on the pathology of transplanted kidney.
