Dr. Marco Seandel is an Associate Professor of Cell and Developmental Biology in Surgery at Weill Cornell Medical College.  Dr. Seandel received his MD/PhD from the State University of New York at Stony Brook, completed his internal medicine residency at New York-Presbyterian/Weill Cornell Medical Center and his medical oncology fellowship at Memorial Sloan Kettering Cancer Center. His lab is keenly interested in the mechanisms by which monogenic and complex disorders become increasingly prevalent in children as a function of the father’s age at the time of conception. Projects in the laboratory relate to cancer risk, autism, and skeletal disorders among others.  The lab uses adult spermatogonial stem cells in vitro, stem cell transplantation, human genomics, and mouse models to understand the origin and mechanisms of human disease.
