Rachel Cianciolo received her veterinary degree and anatomic pathology residency training at the University of Pennsylvania. She went on to do a PhD through a collaborative position between North Carolina State University and GlaxoSmithKline, where she analyzed urinary biomarker profiles and gene expression microarrays in a rodent model of proteinuria. This was followed by a Nephropathology fellowship at the University of North Carolina where she was trained to evaluate human renal biopsies, focusing on histopathology with special stains, immunofluorescence (IF) and transmission electron microscopy (TEM). She was an assistant and then associate professor of Anatomic Pathology for 8 years at the Ohio State University. She has been affiliated with the International Veterinary Renal Pathology Service (IVRPS) since 2006, and she is now a co-Director of that service. The IVRPS evaluates approximately 200 renal specimens each year from numerous species, with the goal of accurate diagnosis using advanced diagnostic modalities such as TEM and IF. Correct categorization of diseases can facilitate prognostication and optimization of therapeutic plans. She joined Zoetis Reference Labs in 2021, where she focuses on submissions from the urinary system as well as other routine surgical biopsy specimens. She is still able to participate in research; her interests include investigation of molecular mechanisms that mediate progression of kidney disease as well as identifying potential targets to slow progression to chronic kidney disease.
