If you have any questions about our program, do not hesitate to reach out to our office. Thank you again for your interest.

Expert program leadership and faculty

The Pediatric Hematology-Oncology Fellowship Training Program at Children’s Hospital Los Angeles is led by Winston Huh, MD. Jamie Stokke, MD, serves as the Associate Program Director and the Director of Medical Education. The Training Program leadership also includes Yves DeClerck, MD, Research Training Director in the CBDI and Associate Director of Training and Education at the USC Norris Comprehensive Cancer Center. Our nationally and internationally renowned faculty share the Program’s commitment to the success of each of our trainees.

Comprehensive training

Our programmatic goal is to prepare you clinically and academically to be a leader in the field and to meet the challenges of rapid advances in science and changes in health care. Our program includes extensive clinical and research training under the supervision and mentorship of program faculty. Training begins with a two-week comprehensive orientation focusing on core subjects in pediatric hematology-oncology and practical instruction in clinical procedures and their interpretation. Fellows then participate in a core curriculum that is tailored over all three years of training. Faculty members lead specialized teams in the following areas: Adolescent and Young Adult Oncology; Benign Hematology; Blood and Marrow Transplantation; Bone and Soft Tissue Sarcomas; Coagulation; Hemoglobinopathies; Leukemia and Lymphoma; Neuro-oncology; Neuroblastoma; Retinoblastoma; and Survivorship and Cancer Control. All fellows work with each of these teams during training. There is a one-week orientation to laboratory techniques at the beginning of the second year to facilitate the transition into laboratory research. This orientation provides technical competency, statistical training and an introduction to laboratory personnel.

Commitment to diversity, equity and inclusion

CHLA’s Diversity and Inclusion Committee is committed to promoting a culture of inclusion and an appreciation for diversity. The Committee supports residents, fellows and faculty across all areas of diversity including, but not limited to race and ethnicity, religion, sexual orientation, socioeconomic status, and gender in order to expand cultural awareness and sensitivity to enrich the services CHLA provides to its diverse patient populations. Tom Belle Davidson, MD, serves as the CBDI’s Diversity, Equity and Inclusion (DEI) Officer and helps guide the division to meet the mission of CHLA’s DEI committee.

Dedicated mentorship

Fellowship Program leadership will provide one-on-one mentoring throughout your fellowship and will assist you during the final stages of training to optimize your successful transition to an academic appointment. Meetings with prospective research mentors start in the winter of year one, a process that culminates in the selection of a primary mentor in the spring. This individual will supervise your research training and provide mentorship towards scientific independence.

Each trainee will have an individually assembled Scholarship Oversight Committee (SOC) to provide specific and structured review of research progress and scholarly activity throughout training. The SOC consists of internal and external clinical and research faculty who are dedicated to helping fellows achieve the highest success in research training and career development.

In addition to Program leadership and research mentors, each fellow will also select a clinical faculty advisor for the three years of training. Faculty advisors provide additional advice and assistance with career planning and professional development, as do other faculty members on an ad hoc basis.

Unparalleled clinical exposure

As one of the largest pediatric hematology-oncology programs in the U.S. located in one of our nation’s most populous regions, Children’s Hospital Los Angeles provides trainees with the benefit of exposure to a vast and diverse patient population. Fellows participate in the diagnosis and management of the full spectrum of conditions in our subspecialty, from the common to the rare. CHLA is a tertiary and quaternary center for the most medically complex children, adolescents and young adults. We are also a referral center for second opinions for routine and unusual cancers, blood disorders and their complications. Fellows have the opportunity to provide continuity of care for patients with a wide variety of hematologic and oncologic diagnoses throughout their training. Such broad clinical exposure under the supervision of faculty specialists with vast expertise leads our trainees to develop knowledge and comfort in the management of the most common and the rarest of cancer and blood disorders.

Research excellence

Our Institute is dedicated to accelerating the pace of laboratory discoveries and to rapidly translating these to improvements in diagnosis, treatment and prevention at the bedside. The institutional environment provides abundant resources and a rich intellectual milieu for research training. We have prominent and highly productive basic, translational and clinical research programs in hematology, oncology and blood and marrow transplantation that serve as the training ground for our fellows. Fellows have opportunities to conduct laboratory research under the mentorship of faculty members located at The Saban Research Institute or at the USC-Norris Comprehensive Cancer Center on the Health Science Campus. There are robust laboratory research opportunities in multiple areas including cancer biology, cancer genetics and DNA repair, gene regulation and epigenetics, tumor microenvironment, immunology and immunotherapy, cell therapy, drug resistance, coagulation and pathophysiology of iron overload. There is also unsurpassed exposure and access to clinical cases, samples and trials, which serve to catalyze laboratory research efforts and provide unique translational opportunities for both physician-scientist and clinical-research trainees. Importantly, we train our fellows within the context of scientific teams that include laboratory and clinical investigators. Our faculty members develop and lead investigator-initiated trials as well as limited institution and cooperative group clinical trials in hematology, oncology, blood and marrow transplantation, cancer control and survivorship. The Institute’s Clinical Trials Program manages more than 1,500 enrollments annually and we are leaders in pediatric research designed to improve cure rates and reduce side effects from therapies for cancer and blood diseases. These trials provide tremendous training opportunities for our fellows.

Additional training opportunities

Trainees have the opportunity to take relevant courses and obtain additional degrees and certificates at USC during their fellowship. This includes the USC Provost’s Postdoctoral Scholars Program for Clinical Residents and Fellows. Under this signature program, fellows receive tuition reimbursement for courses useful for their professional development. Fellows dedicated to a career in clinical research may apply for The Masters of Science in Clinical, Biomedical and Translational Investigations. This program offers an MS degree or a Certificate in Clinical Biomedical, and Translational Investigations and provides advanced training in clinical research methods to translate clinical, biomedical and technological discoveries into advances in population-based, clinical or basic science research.

The George Donnell Society is dedicated to training pediatric physician-scientists to perform innovative and high quality research. The Society includes pediatric residents, subspecialty fellows, graduate students, research post-doctoral fellows and junior faculty at CHLA.

Wellness Committee

To improve overall wellness within the Cancer and Blood Disease Institute and amongst our trainees, a dedicated Wellness Committee was established in 2020. The Committee consists of dedicated faculty members and fellows who meet monthly to design a holistic approach to addressing wellness. We have an award winning fellow-designed Art in Medicine curriculum focused on providing art activities monthly. We have an annual fellows’ retreat focused on humanism in medicine, team building and wellness activities. We have social outings including guided wine tasting, happy hours and an annual trip to a Dodgers game. We have a structured debriefing program following challenging patient encounters, free in house or outpatient mental health services, and dedicated wellness hours guided by CHLA’s Chief Wellness Officer. We provide formal training with the help of our palliative care faculty in communication techniques and end of life issues. We also volunteer as a group to provide services to various local organizations.
