Pediatric Hematology/Oncology Fellowship Program Director, Division of Hematology/Oncology; Associate Professor of Pediatrics, Harvard Medical School
Dr. Kesselheim attended college at the University of Wisconsin and completed her MD at the University of Pennsylvania, where she also earned a master’s in bioethics. Following medical school, she completed residency training in the Boston Combined Residency Program in pediatrics. As a resident, Dr. Kesselheim developed bioethics curricula, and she began to conduct national studies to assess the outcomes of ethics education in pediatric training. Her focus at the interface of ethics, professionalism, and medical education led her to pursue a master’s degree in education from Harvard University, which she completed while a fellow in pediatric hematology/oncology at Boston Children’s Hospital and Dana-Farber Cancer Institute. As an educator, Dr. Kesselheim directs the Pediatric Hematology/Oncology Fellowship Program at Dana-Farber/Boston Children’s, where she also cares for patients with hematologic malignancies. She directs the Master of Medical Science (MMSc) in Medical Education based at Harvard Medical School, a two-year graduate program blending coursework in medical education with mentored research. Dr. Kesselheim’s research investigates the methods and outcomes of physician education in the areas of humanism, ethics, and professionalism. Her projects pertain to the measurement of humanism among pediatric hematology/oncology trainees, integrating interprofessional education into medical school, fostering ownership and accountability in patient care, balancing service and education during training, the hidden curriculum of speaking up, and assessing knowledge of ethical principles among pediatricians and pediatric ethicists. Dr. Kesselheim lives in Boston with her husband, Aaron; son, Max (age 11); daughter, Sydney (age 7); and son, Leo (age 4).

Associate Program Director, Pediatric Hematology/Oncology Fellowship Program; Assistant Professor in Pediatrics, Harvard Medical School
Dr. Gutierrez is a pediatric oncology physician-scientist whose research is focused on deciphering the molecular basis of chemotherapy resistance in T-lymphoblastic leukemias and genetically defined solid tumors. His work has identified new mechanisms of resistance to conventional chemotherapeutics and revealed novel strategies for therapeutic intervention, some of which have translated into active clinical trials. He received his MD from the Perelman School of Medicine at the University of Pennsylvania and completed a pediatrics residency at Children's Hospital of Philadelphia, followed by a fellowship in pediatric hematology/oncology at Dana-Farber/Boston Children’s. His postdoctoral research training was with Dr. A. Thomas Look at Dana-Farber Cancer Institute. As an Associate Program Director, Dr. Gutierrez is focused on advising fellows as they define their research direction and mentorship plans and fostering their development into successful independent investigators.
Pediatric Oncology Chair at Dana-Farber/Boston Children’s, Associate Chief of the Division of Hematology/Oncology at Boston Children’s Hospital
Dr. Armstrong is a pediatric oncologist and leader in leukemia research whose studies have led to several findings that point to promising new therapies. The major focus of his career has been on delineating the biology of childhood cancers and the development of new therapeutic approaches for children with cancer. He has developed a large and robust research program that has focused on the mechanisms of leukemia development and the relationship between leukemia and normal hematopoietic stem cells. He has also developed an interest in the mechanisms by which chromatin modifications control leukemogenic 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 a number of clinical trials that are being assessed in adults and children with cancer. Dr. Armstrong received his MD and PhD from the University of Texas Southwestern Medical School in Dallas, Texas. He performed his residency and fellowship in pediatric hematology/oncology at Boston Children’s Hospital, Dana-Farber Cancer Institute, and Harvard Medical School. Dr. Armstrong’s work has been recognized with the Till and McCulloch Award from the International Society of Experimental Hematology, the Claire W. and Richard P. Morse Research Award from Dana-Farber Cancer Institute, the Wilson S. Stone Award from MD Anderson Cancer Center, the Paul Marks Prize for Cancer Research from Memorial Sloan Kettering Cancer Center, the E. Mead Johnson Award from the Society for Pediatric Research, and the Dameshek Prize from the American Society of Hematology.
