  • 2009 Leonard Berwick Memorial Teaching Award, University of Pennsylvania School of Medicine
Research Interests:

Dr. Maris is a physician-scientist and his basic research program is anchored in the genetics and genomics of neuroblastoma. The four main themes in his lab are (1) determining the genetic events that initiate neuroblastoma tumorigenesis; (2) determining the somatically acquired genomic aberrations and genes responsible for the diverse clinical phenotype observed in patients with neuroblastoma; (3) using genetic approaches to define the unique features of neuroblastoma vascular biology, including functional validation in murine models and applied research with novel compounds targeting neuroblastoma vasculature in partnership with industry; and (4) developing array-based high throughput methods for solid tumor molecular diagnostics.
