He performed his residency and fellowship in pediatric hematology/oncology at Children’s Hospital Boston, the Dana Farber Cancer Institute, and Harvard Medical School. The major focus of his career has been on delineating the biology of leukemia and the development of new therapeutic approaches for cancer. His group studies how chromatin-associated complexes control cancer-causing gene expression and has used this understanding to develop small molecule approaches that he continues to pursue. This work has led to the development of clinical trials that are being assessed in adults and children with cancer.
