About the Fellowship
The fellowship is a three-year program intended to prepare trainees for a career in academic pediatric endocrinology. The program combines clinical endocrinology and diabetes care with excellent opportunities for clinical and laboratory-based research within the division and through close liaisons within the Department of Pediatrics at Children's Hospital Los Angeles, The Saban Research Institute and the Keck School of Medicine at the University of Southern California. The fellowship program has a rich history of excellence in endocrinology and diabetes extending back almost 30 years
Learn More About the Program
The Center for Endocrinology, Diabetes & Metabolism has been named one of the top seven programs in the country by U.S. News and World Report for the last six years in a row. With 13 full-time and three part-time attending physicians, two PhD research faculty, two full-time nurse practitioners, as well as many nurse educators, the fellows are exposed to a wealth of expertise in various aspects of pediatric endocrinology. In addition, fellows have the opportunity to interact with other highly regarded and productive divisions in the hospital that care for patients with diverse pediatric issues. It is the intent of the program that fellows will be well-trained in diagnosis and management of endocrine disorders of childhood, be able to teach and lecture on endocrinology and diabetes, and be familiar with the methodology and interpretation of routine endocrine and relevant genetic laboratory studies. Another critical component of the fellowship is to be able to design and carry out clinical and laboratory investigations.

The fellow will spend 12 months during the fellowship as the "on-service fellow." The service time is generally allocated as follows:
- six months in year one
- four months in year two
- two months in year three
On-service fellows will manage the inpatient endocrine and diabetes service, under the supervision of attending faculty. They will round with pediatric residents and see all consults and primary endocrine and diabetes patients. On-service fellows will also see urgent outpatient consultations, and triage urgent patient phone calls.
When off service, fellows will attend two clinics per week including their own continuity clinic. The continuity clinic will carry on through all 3 years of fellowship and will be staffed by a dedicated attending physician. Non-continuity teaching clinics are preceded by a one-hour conference with the attending, which is spent discussing cases to be seen and endocrine/diabetes topics of interest. Incorporated in teaching clinic schedule are our multidisciplinary clinics including comprehensive CAH and hyperandrogenism clinic, Turner syndrome clinic, EMPOWER weight management clinic, type 1 and type 2 diabetes clinics, rare bone disorder clinic, neuro-oncology Clinic, and thyroid nodule clinic. In addition, fellows have the opportunity to do rotations in other CHLA divisions, including but not limited to Lipid clinic (Cardiology), Transgender clinic (Adolescent Medicine) and Genetics clinic.
Fellows cover the service on weeknights and weekends all 3 years, in rotation with one another, resulting in being “on call” one in every five or six nights and weekends. Call is primarily from home, though weekend call involves morning inpatient rounds, and fellows are expected to be available to come into the hospital for rare emergencies.
Fellows engage in research throughout their training (for a total of 22 months while "off service"). In their first year, fellows will choose their research project and mentors, in coordination with the fellowship director. They will lay the groundwork for their project(s), and choose their Scholarship Oversight Committee, which will monitor their scholarly progress throughout their fellowship. During the second and third years, fellows will focus primarily on their research project(s). Clinical research projects are expected to be hypothesis-driven and rigorously performed. Bench research should involve a discrete project in which the fellow does the majority of the hands-on work. Both types of research should lead to one or more first-authored publications for the fellow. Fellows are encouraged to attend and present their research at institutional, local, and national scientific meetings, and the division provides clinical coverage and financial support for these activities. Fellows are required to apply for at least one grant during their fellowship.
Endocrinology fellows have the opportunity to participate in a wide variety of clinical and laboratory-based research projects. Fellows develop their own projects, building on one of a number of ongoing projects within the division, or with one of collaborators in other divisions at Children’s Hospital Los Angeles or in the Keck School of Medicine of the University of Southern California.

Class of 2018
Alaina Vidmar, MD
Medical College of Wisconsin
Children’s Hospital of Wisconsin
Having a sister with type 1 diabetes and Hashimoto’s thyroiditis, I was always amazed at what an impact the loss or gain of one hormone could be on how a body functions. During medical school and residency I became fascinated with the pediatric obesity epidemic and interested in exploring ways to create innovative strategies for weight management. Mobile health technologies allow young people to interact with their health in a way they understand. My research in fellowship has focused on studying the effectiveness of an addiction based mobile health weight management intervention for adolescents. Through my research and clinical experiences in fellowship, I have developed a passion for findings creative solutions to the problems our patients face to improve their health and quality of life.
Jonathan Weber, MD
Temple University School of Medicine
Rush University Medical Center
During my Pediatrics rotation in my 3rd year of medical school, I had to opportunity to participate in the care of a newborn baby with congenital adrenal hyperplasia. This case sparked my interest in pediatric endocrinology. I have carried this threat through my training, and my current research focus is on newborns and infants with classic CAH, looking into adrenomedullary function and how this relates to clinical outcomes.

Sara Akhtar MD
St. George’s University School of Medicine
Cleveland Clinic Foundation
Born and raised in Minneapolis, MN, I moved west after falling in love with the program at CHLA. I always loved pediatrics, but my passion for endocrinology really came during residency where I got to experience new onset diabetes and endocrine mysteries first-hand. It is the intricacies of feed-back loops as well as checks and balances in Endocrinology that drew to me the field. After seeing my first few patients with debilitating bone disease at CHLA, I decided to pursue research in pediatric metabolic bone disorders with a focus on neuromuscular diseases. It is my hope to help pioneer better treatment options for these spirited and resilient patients.
Marwan Bakhach MD
American University of Beirut, School of Medicine
Cleveland Clinic Foundation
Endocrinology has always been a very interesting topic for me since I started pursuing my medical career. During residency, I was influenced by mentors in the Pediatric Endocrine division which, in turn, prompted me to be involved in endocrine-related research projects and confirmed my desire to pursue a career in pediatric endocrinology. Currently, my fellowship research project involves studying home telemedicine appointments (CoYoT1 Clinic) designed to respect the multiple demands of young adults with type 1 diabetes (T1D), and its impact and efficacy in T1D care.

Amy Seagrove, MD
Albert Einstein College of Medicine
University of California Irvine/ Children’s Hospital Orange County
I grew up in Concord, NH and then went to college at Fordham University in Bronx, NY. During college I double majored in biology and history and developed a passion for working with children so I decided to go to medical school and become a pediatrician. I stayed in the Bronx for medical school and went to Albert Einstein College of Medicine. While studying medicine in the Bronx, I encountered many patients with diabetes and obesity and become interested in the field of endocrinology. I got tired of the cold, dreary winters of the Northeast and decided to go to Southern California for residency where I trained at UC Irvine/Children’s Hospital of Orange County. Residency confirmed my love of endocrinology and I decided to stay in sunny Southern California for fellowship. I continue to be interested in diabetes and obesity and I am currently doing research looking at food choices in patients with Type 1 Diabetes Mellitus.
David Tsai MD
Albany Medical College
Kaiser Permanente Los Angeles
I studied neurobiology during my undergraduate years and always had an interest in psychology. Combined with a love for technology, I pursued pediatric endocrinology to explore better ways of helping children and their families overcome psychological barriers associated with type 1 diabetes and other chronic endocrine disorders.
