Our Pediatric Fellows

"duPont is an absolutely wonderful place to train. I have had the privilege of training here for both residency and fellowship. The faculty are extremely supportive and invested in our education. As a fellow, you get first-hand experience in taking care of a wide variety of hematology and oncology patients. You are given both the autonomy and support needed to feel equipped to become a successful pediatric hematologist/oncologist."

— Renee Gresh,

"I chose this fellowship for the diversity of experiences and the incredible faculty. We have the opportunity to work closely with very talented faculty to care for a variety of patients. In addition, we are involved with quality improvement projects, research and interdisciplinary teams that teach us about systems based practice. I couldn’t ask for a better place to train."

Program Details

Our Program

Our clinical staff and patient populations provide a broad exposure to all areas in pediatric hematology/oncology including:
  • hematological diseases such as sickle cell anemia and variants, the thalassemias, nutritional anemias, bleeding disorders, hypercoagulable disorders, WBC disorders, platelet disorders, hemophagocytic lymphohistiocytosis and related histiocyte disorders
  • oncological diseases including solid tumors such as sarcomas, neuroblastoma, retinoblastoma and others; a wide range of leukemias and lymphomas and a wide variety of malignant and low-grade brain tumors
  • A FACT accredited bone marrow transplant service including autologous and allogeneic (matched and mismatched) transplants for oncologic, hematologic, immunologic and storage diseases
  • survivorship clinic and services for survivors of childhood cancer

Fellows are expected to provide complete care for many of these patients with these varied diagnoses and continue to follow their primary patients throughout their fellowship training.


Pediatric hematology/oncology fellowship training programs are three years in length. The majority of the first year is spent learning clinical medicine, with some time set aside for research and clinical electives. First year clinical rotations include inpatient hematology/oncology service, inpatient blood and bone marrow transplant service, outpatient hematology/oncology clinic, outpatient bone marrow transplant clinic and tissue pathology/blood bank and lab medicine. Electives, research and vacation are also part of the first year schedule. There is no in house call.

Years two and three are dedicated to scholarly work on an original research project. Clinical and lab research projects are coordinated through the Nemours Center for Childhood Cancer Research. Research opportunities are available on campus or at our associated sites including the University of Delaware and Thomas Jefferson University in Philadelphia.


Weekly conferences cover a wide range of clinical and research topics from tumor boards to journal clubs to specialty conferences such as sickle cell conference. Fellows are expected to attend many of these meetings.

Research Opportunities

Research Opportunities

Nemours is a leader in hematology/oncology research. Our Nemours Center for Childhood Cancer Research (NCCCR) coordinates research activities for fellowship trainees. Our Nemours Center for Cancer and Blood Disorders (NCCBD) uses state-of-the-art technology and resources to perform pediatric bone marrow and stem cell transplants. You’ll be able to explore numerous opportunities on our campus and at our associated sites, including the University of Delaware and Sidney Kimmel Medical College at Thomas Jefferson University (TJU).

As an integral part of your training, you’ll have broad medical research exposure that increases over the program’s 3-year term. While your first year focuses primarily on clinical work, you’ll also have an intensive orientation course that covers research methods, teaching techniques, outcomes research, evidence-based medicine, human subjects training, and other topics. You’ll be encouraged to start thinking about and arranging research projects early, as this will be your focus during the second and third years.

Original, scholarly research is a required element of fellowship training in pediatric hematology/oncology. We have many productive research labs that welcome fellows and are able to train them in lab science and mentor them to master the process of doing original, bench research. We have academic affiliations with Thomas Jefferson University in Philadelphia as well as the University of Delaware that expand our research opportunities. Clinical research opportunities are available as well including epidemiological studies, quality improvement and safety projects. Some qualified fellows in our pediatric hematology/oncology fellowship training program may be able to satisfy program requirements for scholarly work by pursuing additional studies culminating in a graduate degree.

As you shift more toward research activities, you’ll continue to follow your primary patients on regular outpatient clinic days. Nemours provides advanced research facilities and resources on campus, along with encouragement and guidance from professionals.
