Scientific Interests
Dr. Julian Martinez is interested in understanding the common signal transduction pathways across cancer predisposition genetic syndromes, in particular Noonan, Costello, Craniofaciocutaneous, Neurofibromatosis and overgrowth syndromes (Sotos, Beckwith-Wiedemann, Weaver, Simpson-Golabi-Behmel) and their associated malignancies: neuroblastoma, sarcomas, and leukemias.
To this end, Dr. Martinez utilizes Drosophila melanogaster as a model organism in which to study the cellular and genetic mechanisms that lead to oncogenesis due to the signal transduction pathways disrupted in these syndromes.
