    Dr. Judkins is recognized for his diagnostic expertise and research in pediatric brain tumors, particularly embryonal CNS neoplasm including atypical teratoid/rhabdoid tumors (AT/RT). He is a reviewer of pediatric brain tumors for Children’s Oncology Group. He also is recognized for his work in nonneoplastic pediatric neuropathology, where his focus has been on developmental malformations and the neuropathology of seizure disorders. Dr. Judkins has developed unique expertise in digital pathology and is working to build tools to integrate bioinformatics and pathology image data analysis.
    Dr. Judkins received a bachelor’s degree (1991) from State University of New York Geneseo, graduating Summa Cum laude. He received his medical degree (1996) from the University of Rochester School of Medicine in New York. Dr. Judkins trained at the Hospital of the University of Pennsylvania, where he completed residency training in anatomic pathology (1996-97), and served as chief resident (1998-99). He completed fellowships in neuropathology (1999-2001, the Hospital of the University of Pennsylvania) and forensic pathology (2001-02, Office of the Medical Examiner in Philadelphia and MCP Hahneman University).

    Dr. Judkins is board certified in anatomic pathology, neuropathology and forensic pathology. He joined the faculty of the University of Pennsylvania School of Medicine as an assistant professor in the Department of Pathology and Laboratory Medicine and the staff of CHOP as a neuropathologist in 2002.

    He currently serves in editorial positions at a variety of journals and publications, including Brain Pathology, the Journal of Neuropathology & Experimental Neurology and Acta Neuropathologica.

    Prior to joining our hospital, Dr. Judkins served as the chief of the Division of Neuropathology, Department of Pathology and Laboratory Medicine at Children’s Hospital of Philadelphia. He also served as the director of their Pathology Core Laboratory and assistant professor of Pathology and Laboratory Medicine at the University of Pennsylvania School of Medicine. He also has made significant contributions to both the Children’s Hospital of Philadelphia Research Institute and the Department of Pathology and Laboratory Medicine. He developed the Pathology Core Laboratory to offer services and support to researchers at CHOP, as well as the broader University of Pennsylvania research community.
