Research Interests

For many years, I have been involved in studies of childhood tumors and defects of neural crest cell migration. More recently, our lab has concentrated in the study of a neural crest disorders involving melanocytic proliferations, especially a disorder called neurocutaneous melanocytosis. Patients with this condition are born with large pigmented nevi (moles) and later develop meningeal/brain melanocytic proliferations. We are investigating the role of Epithelial-Mesenchymal Transition in the development of these abnormal proliferations. In addition, as a member of the Scientific Advisory Board of Nevus Outreach, Inc., a Pathology Consultation service for conditions related to Giant Melanocytic Nevi and Neurocutaneous Melanocytosis is offered.

Another condition within our diagnostic interests is Hirschsprung disease (congenital megacolon), in which neural crest-derived ganglion cells are not present in the colonic nervous system, leading to chronic constipation.

Other avenues of research interest include the early pathology of cancer predisposition syndromes. We are interested in seemingly trivial lesions that may foretell an increased cancer predisposition in the pediatric patient.

In addition, the pathology of pediatric testicular lesions, including Disorders of Sex Development is a current focus of our efforts. We collaborate with our colleagues in Pediatric Endocrinology, Pediatric Urological Surgery, Genetics, and others, to support a Clinic on these disorders. We also have collaborations with other institutions to develop new diagnostic approaches to these conditions. A Consultation service for Testicular Pediatric Pathology is offered.
