Pediatric interventional neuroradiology
Todd Abruzzo, MD, has helped establish a national referral center for pediatric vascular malformations, hereditary hemorrhagic telangiectasia, and retinoblastoma at Cincinnati Children’s Hospital Medical Center. He plays a major role in the endovascular treatment of children at Cincinnati Children’s. Through close collaboration with other members of the Fetal Care Program at Cincinnati Children’s, he has helped to develop a comprehensive care plan for children with vein of Galen malformations and other congenital vascular anomalies. While working with other physicians, he has helped build a nationally recognized program for the treatment of retinoblastoma with intra-arterial chemotherapy.

St. Baldrick’s Foundation Scholar
Sontag Foundation Distinguished Scientist
Assistant Professor, UC Department of Pediatrics
Lionel Chow, MD, PhD, received his medical and graduate degrees from McGill University in Montreal, Canada, where his research focused on the regulation of T-lymphocyte signaling by the intracellular tyrosine protein kinases Lck and Csk.
Following his clinical training in pediatrics and pediatric hematology / oncology at the Hospital for Sick Children in Toronto, Canada, he moved to St. Jude Children’s Research Hospital in Memphis, Tenn., to pursue his research interests.
Chow's research interests have been centered on glioblastoma multiforme, a particularly devastating form of cancer in adults and children. His work has resulted in the development of a number of novel and robust laboratory models for this disease. Using these models and interfacing with clinical trials in the Neuro-Oncology Program as well as those from national consortia such as the Children's Oncology Group (COG) and the Pediatric Brain Tumor Consortium (PBTC), Chow’s laboratory will continue research in this area with the goals of better understanding the origins of this form of cancer and improving patient outcomes.

Preclinical testing in neurofibromatosis tumors
Nancy Ratner, PhD, is interested in understanding mechanisms of peripheral nerve tumor (neurofibroma) formation in neurofibromatosis type 1 (NF1), a common inherited disorder in which children are predisposed to cancer of the nervous system, to learning problems, bone disorders, and other cancers. She identified EGFR and MEK as potential therapeutic targets in NF1 peripheral nerve tumorigenesis, and has developed cell culture and mouse models of NF1 nerve tumorigenesis. Her laboratory has also used analysis of gene expression to identify critical genes in neurofibroma and their malignant derivatives, MPNST.
Dr. Ratner received her bachelor's from Brown University, her doctorate from Indiana University, and was a postdoctoral fellow at Washington University in St. Louis. She was a member of the faculty at the University of Cincinnati from 1987 to 2004. Dr. Ratner is currently a professor in the Department of Pediatrics, Cincinnati Children’s Hospital Medical Center, University of Cincinnati, and the program leader for Cancer Biology and Neural Tumors Program in the Cancer and Blood Diseases Institute where she holds the Beatrice C. Lampkin Endowed chair in cancer biology and serves as PI of the NINDS P50 “Cincinnati Center in NF Research.”
Dr. Ratner is an active member of the International Consortium on the Molecular Biology of NF1, NF2, and Schwannomatosis and was a member of the advisory board for the National Neurofibromatosis Foundation (now Children’s Tumor Foundation) from 1989 to 2007. She chaired the Department of Defense Neurofibromatosis Research Program Integration Panel in 2008, and currently serves as a member of the James McDonnell Brain Tumor Research Advisory Board. She received the von Recklinghausen Award from the Children’s Tumor Foundation in 2010 and the Jacob K. Javits Neuroscience Investigator Award (NIH-NINDS MERIT Award) in 2014.
