Prof. Erin Rudzinski completed her undergraduate degree at Berry College, graduating magna cum laude in 1999. She obtained her medical degree from the Medical College of Georgia in 2003. Dr Rudzinski completed her anatomic and clinical pathology residency at Vanderbilt University Medical Center in 2007. Following her residency, she completed an additional anatomic pathology fellowship year at Vanderbilt, followed by a pediatric pathology fellowship at Seattle Children’s Hospital/University of Washington Medical Center. She joined the staff at Seattle Children’s Hospital in 2009, and she is currently a Clinical Associate Professor in the Department of Pathology at the University of Washington. Dr Rudzinski specializes in pediatric solid tumors, with a focus on pediatric soft tissue tumors. The goal of her research is improving the morphologic and molecular classification of pediatric soft tissue tumors, including the development of ancillary diagnostic biomarkers (ie. immunohistochemistry). Dr Rudzinski is an active member of the Children’s Oncology Group, the College of American Pathologists, and the Society for Pediatric Pathology.
