Hematology and Oncology Fellowship

Our three-year fellowship, a combined program of Oishei Children’s Hospital and Roswell Park Comprehensive Cancer Center, provides training in pediatric hematology and oncology through strong clinical and research opportunities.

In our program you’ll benefit from training components including:

  • an intensive orientation period, with shared service with a senior fellow, that provides a smooth transition into your role as a fellow in a new clinical setting
  • grand rounds at Oishei Children’s Hospital and Roswell Park Comprehensive Cancer Center, which provide the newest information in pediatrics and oncology
  • fellow-directed projects that teach you the processes of developing quality improvement projects and obtaining Maintenance of Certification credit for your future board certifications
  • Trainee Core Oncology Seminar, which includes lectures on ethics, statistics and CV writing
  • weekly lectures — delivered by faculty, fellows and guest speakers — that deepen your knowledge on a range of topics and sharpen your presentation skills

Clinical Training

During your first year in our program, you can expect to undertake intensive training in hospitals and clinics.

In your first year, we’ll expose you to:

  • inpatient and consultation service at Oishei Children’s Hospital
  • clinic at Roswell Park Comprehensive Cancer Center and subspecialty clinics
  • experience at the Hemophilia Center of Western New York and blood banks

The experience you gain will strengthen your understanding of areas including:

  • radiation oncology
  • bone marrow transplantation
  • coagulation
  • palliative care/pain service
  • pathology, including flow cytometry and cytogenetics

Continuity Clinic

As the primary provider for patients with oncology and hematology diagnoses, you’ll gain significant experience providing longitudinal care. You’ll participate in continuity clinic throughout your fellowship training, and we’ll increase your responsibilities as you progress through the program. You can also expect to take calls from home for the duration of your training.

Multidisciplinary Experience

We emphasize a multidisciplinary approach in the care of patients with complex medical conditions; input from a variety of specialists is crucial for proper cancer care and management.

In our program, you’ll be exposed to multidisciplinary tumor boards for neuro-oncology, oncology and complex hematology patients. You can expect to learn about how professionals from different specialties — radiologists, radiation oncologists, radiologists, surgeons, pathologists and our extended team — participate in comprehensive patient care.

Our curriculum enables you to attend multidisciplinary clinics over the course of training. You’ll have opportunities to learn how each specialty supports the care of children with complex diagnoses. If our clinics stimulate your enthusiasm to gain further knowledge, we encourage you to expand your skill set by joining additional clinics.

Our clinics include:

  • brain tumor clinic
  • neurofibromatosis clinic
  • sickle cell disease clinic
  • comprehensive hemophilia clinic
  • vascular anomaly clinic
  • survivorship clinic


Your second and third years of fellowship training will be primarily dedicated to research. You can conduct basic or translational research with a number of our physician-scientists and scientists or in conjunction with collaborators from other fields.

Our faculty members have diverse research interests in areas including:

  • thrombosis and thrombophilia
  • hemoglobinopathies
  • leukemias and lymphomas
  • solid tumors
  • bone marrow transplantation
  • late effects of therapy
  • issues affecting adolescents and young adults
  • oncofertility

We have a strong psychosocial team — including two psychologists, social work support and an integrative medicine practitioner — that allows for multiple avenues of research. Additionally, Roswell Park Comprehensive Cancer Center offers didactic and research opportunities that provide a foundation for a research career.

We encourage you to attend and present your research at local and national meetings.

Our Facilities

Oishei Children’s Hospital and Roswell Park

Our program equips you with experience providing inpatient care in a dedicated unit — located in the state-of-the-art Oishei Children’s Hospital — specifically designed for the care of immunocompromised patients or those with hematologic needs.

Training in an outpatient clinical setting, located at Roswell Park Comprehensive Cancer Center, will give you experience working in an environment with infusion and transfusion facilities. Additionally, adolescent and young adult programs, as well as onco-fertilityintegrative medicine and survivorship programs are integral to our training.

These training sites are members of Children’s Oncology Group and participate in the Dana-Farber Cancer Institute ALL Consortium.

Hemophilia Center of Western New York

Through our affiliation with the Hemophilia Center of Western New York, you’ll increase your skill in caring for patients with hemophilia and other severe bleeding disorders.

Our Faculty

Our faculty members have a breadth of knowledge of many facets of our subspecialty. Our strengths in hematology, oncology and stem cell transplantation — all in one department — allow for an exhaustive education for our trainees.

You also have the opportunity to collaborate with researchers across the Buffalo Niagara Medical Campus. As a smaller fellowship program, we have the ability to tailor your training to your interests and future career plans.

To Apply

The postdoctoral education prerequisite is three years of general pediatric residency training.

Candidates should apply through ERAS and enter the Pediatric Hematology/Oncology Match through NRMP.
