Pediatric Rheumatology Fellowship

About the program

The Fellowship Program in Pediatric Rheumatology is a three-year program designed for physicians trained in pediatrics and selected on the basis of excellence in their credentials and training programs.

Our program combines a one-year clinical experience followed by at least two years of scholarly work, which can include advanced training in basic, translational or clinical research, while continuing a longitudinal patient care experience. The program is led by a broadly experienced faculty who will train physicians to be pediatric rheumatologists and leaders in pediatric rheumatology.

Unique information about the program

An independent Division of Rheumatology was established in 1999 within the Department of Pediatrics. In 2000, the American College of Graduate Medical Education (ACGME) accredited the Rheumatology Fellowship Program. We have eleven pediatric rheumatology faculty members and two fellowship slots available each year. Our faculty are actively engaged in both basic and clinical investigation, and have a longstanding commitment to Children’s Arthritis and Rheumatology Research Alliance's (CARRA) efforts. Additionally, CHOP Rheumatology  has a long-term involvement in participation and leadership within the ”Pediatric Rheumatology Care & Outcomes Improvement Network (PR-COIN) Network.

Fellows and nurses celebrating National Nurses Week Fellows and nurses celebrating National Nurses Week Clinical training occurs in our busy outpatient clinic, as well as on the inpatient side with both our primary rheumatology service and a robust consult service. CHOP not only serves as the main pediatric care site for much of Philadelphia, but also welcomes patients from throughout the mid-Atlantic region, the United States, and the world. We conduct three multi-disciplinary clinics which fellows actively participate in, the Uveitis Coordinated Care Clinic, the Lupus Integrated Nephritis Clinic and the Immune Dysregulation Clinic. In addition to these, we have an Amplified Musculoskeletal Pain Multidisciplinary Clinic which is available for interested fellows. Rheumatology clinicians are supported by 5 nurses and 2 social workers, including a dedicated lupus social worker.  

Fellows practicing their ultrasound skills Fellows practicing their ultrasound skills Musculoskeletal ultrasound, arthrocentesis, and intraarticular corticosteroid joint injections are commonly performed. In addition to clinic-based training, fellows enroll in ultrasound educational offerings at the ACR Annual Scientific Conference or at the CARRA Annual Conference. We currently have two Sonosite M-MSK system devices for use in our clinic, which has enhanced our diagnostic and therapeutic capabilities.

Pediatric rheumatology has a strong clinical and research relationship with the Penn Division of Adult Rheumatology. We have shared conferences, and pediatric fellows attend adult clinics periodically. Importantly, we have a shared NIH fellowship training grant (T32) and have recently developed a Medicine-Pediatrics Rheumatology Fellowship. 

Specific information by years and/or rotation

First year

Fellows become proficient in the history, physical exam, differential diagnosis, diagnostic evaluation, and treatment of pediatric rheumatic diseases. Sensitivity to psychosocial aspects of chronic illness is emphasized.

First-year fellow teaching residents on the Rheumatology primary service First-year fellow teaching residents on the Rheumatology primary service First year fellows spend five months each on inpatient and outpatient services, and spend four weeks on elective or research rotations. Elective rotations will be set up from a variety of outpatient clinics, depending on the fellow's interests (such as sports medicine, immunology, or our multidisciplinary uveitis clinic). First year fellows have a once-weekly continuity clinic in which they follow patients for whom they are the primary rheumatologist.

The fellows share night and weekend care with the pediatric rheumatology attending. Additionally, the fellows prepare multidisciplinary conferences and take a major role in teaching residents and students rotating through the service.

During the first six months, under the mentorship of the faculty, the fellows consider available research training opportunities. In the second half of the first year, the fellows develop an appropriate research training plan and identify a research mentor.  

Second and third year

Clinical responsibilities during the second and third years consist of a longitudinal patient care experience in continuity clinic and 4-6 weeks of inpatient service. Fellows are encouraged to take advantage of a number of opportunities to further their teaching skills with CHOP residents, Penn medical students, and other hospitals within the region. They participate in an adult rheumatology elective through the University of Pennsylvania Department of Rheumatology as well as an amplified musculoskeletal pain elective.  

Faculty precepting in fellows’ clinic Faculty precepting in fellows’ clinic The majority of time in the second and third years is devoted to research training — a critical component of the fellowship program. Fellows interested in basic/translational science may enroll in courses offered through the UPENN Graduate Program in Immunology and work as a post-doctoral fellow in their mentor’s laboratory. Fellows planning on a career in clinical research can enroll in the two-year Master of Science in Clinical Epidemiology (MSCE) Program at the UPENN Center for Clinical Epidemiology and Biostatistics (CCEB).

Those seeking formal training in translational research may enroll in the two-year Masters in Translational Research (MTR) Program.

If you have other scholarly interests, please let us know so we can connect you with opportunities across the extensive CHOP and Penn campuses.

Didactic program

  • Division chair holding an impromptu teaching session in the fellow workroom Division chair holding an impromptu teaching session in the fellow workroom Each week, faculty and fellows participate in a 60-minute didactic session, and a 30-minute inpatient and challenging outpatient discussion. Our didactic curriculum is designed on a three-year cycle to ensure that fellows have exposure to outstanding CHOP and UPenn faculty with diverse expertise. Dr. Mehta reviews the Petty Textbook of Pediatric Rheumatology chapters each week with the first-year fellows.   
  • Every month, fellows lead a journal club with guidance from faculty.  Major current or recent manuscripts in basic or clinical investigation relevant to rheumatic diseases as well as seminal articles are prioritized.  Fellows receive feedback on their knowledge of the content in the manuscript and their analysis of study methods.
  • Fellows participate in all divisional QI activities. Fellows learn improvement methodology and tools to systematically shepherd projects through define, diagnose, test/implement, and sustain phases. We actively participate in the Pediatric Rheumatology Care & Outcomes Improvement Network (PR-COIN), which focuses on QI training and improvement activities.  One fellow has the opportunity to attend each biannual PR-COIN conference.  Fellows have access to the Institute for Healthcare Improvement (IHI) curriculum, and a resident/fellow QI lecture series.
  • We augment didactic sessions with interdisciplinary conferences with Radiology, Nephrology, Dermatology, Neurology, and UPenn Rheumatology.  With guidance from attendings, fellows organize case presentations during these interdisciplinary conferences.  Additionally, fellows are encouraged to attend the weekly Immune Dysregulation and monthly Interstitial Lung Disease interdisciplinary conferences.
  • CHOP and, specifically, our division have a strong interest in helping fellows and faculty identify and address health disparities. We have a four-part didactic series, including 1) The role of implicit bias in patient care; 2) rheumatology health disparities and social determinants of health; 3) Using QI methodology to address healthcare disparities; 4) Communication skills for a diverse patient population.
  • At the start of fellowship, we conduct a three-day didactic Introduction to Fellowship, focusing on major pediatric rheumatic diseases, therapeutics, laboratory testing and imaging, and how to be an effective consultant pediatrician.  In addition, from September through December of each year, fellows attend the Immunology Lecture Series. Led by Dr. Behrens and Dr. Canna, and taught by leading basic investigators, this 10-lecture curriculum covers innate and adaptive immunity and prepares fellows to understand the pathophysiology of rheumatic diseases and rational choice of disease modifying and biologic therapies.
  • Fellows are encouraged to participate in the Department of Pediatrics Fellowship Core Curriculum with a variety of fellows from across the institution. 
  • Fellows are encouraged to integrate opportunities for patients and families to participate in clinical research (trials, national registries, ongoing interventional and non-interventional studies) in the everyday clinical care setting.    

Department of Pediatrics Fellows’ core curriculum

The Department of Pediatrics organizes a common core curriculum for all fellows at CHOP. Fellow Core Curriculum will cover multiple topics relevant to all pediatric subspecialty fellows, including professional development. Core Curriculum begins with sessions during the Departmental New Fellow Orientation and continues with multiple offerings throughout the year. Topics included include:

  • Quality Improvement Methodology
  • Half day retreats by year of training
  • Orientation First Year: Time management, Fatigue mitigation, Introduction to CHOP and Penn, Wellbeing, Tips and Tricks to Success as a Fellow; Diversity, Equity, and Inclusion
  • Spring First Year: Grant funding, Mentee-Mentor Relationship, Research Design, Advanced library skills
  • Second Year: Leadership, Communication skills, Presentation, Health Care Disparities, Teaching skills
  • Fall Third Year – Success in the Job Search: Job search overview, interview skills, CV and Cover letter workshop,
  • Spring Third Year – Transition to Attending: Leadership skills, Work-life integration, Time management, Billing, Life-long learning, Personal Finance

These sessions occur multiple times per year and offer the added benefit of allowing fellows from different subspecialities an opportunity to engage and network over the course of their training at CHOP. Additional educational and community building events are offered by the Fellows Association (FA). The FA is a volunteer organization that is comprised of multi-disciplinary senior fellows and a faculty advisor. The FA’s mission is dedicated to representing the interests of subspecialty fellows at CHOP and to promoting the continuous improvement of their training experience.

Julia Rood, MD, PhD: Julia is a fourth-year fellow in the Accelerated Research Pathway. She grew up in Maryland but returned to her family's midwestern homeland for her undergrad years, studying biology and math at St. Olaf College in Minnesota. She found her love for translational research while working at the NIH, prompting her to pursue an MD/PhD at Penn. She has a fondness for viral immunology but discovered her interest in pediatric rheumatology while completing her graduate studies in Dr. Behrens' lab and pediatrics residency at CHOP. Her research interests include dysregulated antiviral immune responses and antigen presentation. When not at work, she can be found in the pool, biking through Fairmount Park and Wissahickon, or exploring Philly's many parks with her husband and 20 month-old daughter.

Sarah Bayefsky, MD: Sarah is a fourth-year fellow and has the honor of being the first combined pediatric & adult rheumatology fellow at CHOP/Penn.  She attended college at Harvard, went to medical school at the Zucker School of Medicine at Hofstra/Northwell, and completed her Internal Medicine-Pediatrics (Med-Peds) residency at Vanderbilt. As an intern, she became fascinated by rheumatology after spending time with a pediatric patient with vasculitis and an adult patient with myositis. As she progressed through residency, she realized that the complexity of cases, longitudinal care, holistic approach, interdisciplinary nature, collegial environment, and lifelong learning that the field of rheumatology affords made for a perfect fit. She is interested in medical education and loves to teach residents and medical students. Outside of work, she can be spotted picnicking by the Schuylkill River, traveling to faraway lands (in the absence of a global pandemic), cheering for the Toronto Blue Jays baseball team, and trying to speak with you in foreign languages. 

Dori Abel, MD: A third year fellow, Dori grew up outside of Philly, where she developed her Philly pride and knew she would always return (although she also loves NYC - you’re allowed to love both)! She earned her bachelor’s degree from Duke University, then gradually made her way back up the east coast, completing her medical education at Georgetown and her pediatric residency training at Columbia in NYC. She and her friends describe her as an enthusiastic and passionate person, especially when it comes to her love for rheumatology and The Parent Trap. The long-term relationships, diagnostic complexity, multisystem involvement, novel treatment advances, and close-knit pediatric rheumatology community drew her to the field, and she loves sharing her passion with trainees through mentoring and education. She is currently pursuing a Masters in Health Policy with a Concentration in Healthcare Quality and Safety. Her current research and quality improvement interests relate to health equity, medication adherence, and self-management support in rheumatology. Outside of work, she enjoys an active lifestyle including hiking beautiful mountains and biking, and she will happily whoop anyone into shape during her Yoga Sculpt fitness class! 

Adam Mayer, MD: Adam is a third-year Med/Peds rheumatology fellow. He hails from the distant land of Baltimore, MD.  For his undergraduate studies he attended the University of Maryland Baltimore County (UMBC) where he studied Biology and German.  Fun fact, UMBC has one of the top chess teams in the country, but not much in terms of other (actual) sports.  He then came to Philadelphia for medical school at Penn followed by Med/Peds residency at Penn/CHOP.  After 10 years, Philly is truly his new home!  Adam chose to stay at Penn/CHOP for rheumatology fellowship given the breadth of interesting pathology, high quality research and exceptional mentorship.  Adam is interested in adult and juvenile spondyloarthritis, with a specific interest in understanding optimal diagnostics and therapeutics for patients with IBD-associated arthritis.  When not in the hospital, Adam can be found telling dad jokes (to his wife's chagrin), going on hikes with his wife and baby boy Oliver, and watching every type of football (i.e. football and soccer). 

Sarah Capponi, MD: Sarah is a third-year Med Peds Rheumatology fellow . She went to Johns Hopkins for college and majored in Writing Seminars, and then migrated back to her home state of Pennsylvania for medical school at Jefferson and Med Peds residency at Penn and CHOP. She is interested in transitions of care, medical education, and quality improvement for medically complex Rheumatology patients. She loves playing tennis, recreational bike riding, eating at all the amazing Philadelphia restaurants, watching reality TV, and hanging out with her husband, daughter Nora, and mini Australian pup Theo. 

Hallie Carol, MD: Hallie is a second-year fellow, who was born and raised in Massachusetts. Her love of the east coast and outdoor activities was solidified at Bowdoin College, where she studied Biochemistry. She completed her medical school training at Columbia University, followed by pediatric residency at Lurie Children's hospital in Chicago. Hallie was initially drawn to Rheumatology for its close tie with the immune system and diagnostic dilemmas. She knew CHOP was for her after she met the enthusiastic, welcoming faculty and heard about the immune dysregulation program. She is particularly interested in autoinflammatory diseases andis studying the innate immune system in the Canna Lab . Hallie considers herself a Trader Joe's enthusiast. She loves the outdoors, especially enjoying an afternoon along the Schuylkill river (which must involve picnicking and/or hammocking). When stuck inside, she is known to brew kombucha and watch F1. 

Anna Costello, MD: A second-year fellow, Anna is from Connecticut originally and attended Brown University as part of the Program in Liberal Medical Education for undergraduate and medical school. She completed her Pediatrics Residency at CHOP and then survived a tumultuous chief year during the start of the COVID-19 pandemic. She then worked as a Pediatric Hospital Medicine Attending at CHOP for two years before applying for Rheumatology fellowship. She is so excited to continue training with the amazing group at CHOP. She wanted to stay because CHOP offers an amazing balance of being the local hospital for the city of Philadelphia and being a referral center for patients from all over the world. This lets you learn about everything from bread-and-butter cases to incredibly rare diseases and provides you with incredible clinical training. She is a student in the Master’s in Health Policy Research program at UPenn and is a Diagnostic Excellence fellow with the Society to Improve Diagnosis in Medicine. During her second and third year, she hopes to study diagnostic delay in JIA. Her husband is a Pediatric sports medicine attending at CHOP andthey also have adaughter named Zoe who was born a couple of months prior to the start of fellowship! They love taking family walks around all the beautiful trails and parks in the Philly area.  

Sarah McCuaig, MD, PhD: Sarah is a first-year fellow from Waterloo, Ontario, Canada.  She has had a long-standing scientific passion for immunology and discovered her clinical love of pediatric rheumatology as a medical student. She completed her PhD (DPhil) at the University of Oxford with Fiona Powrie studying mucosal immunology. She then completed her medical degree at UPenn and her Pediatric Residency at CHOP. She is on the Accelerated Research Pathway and hopes to pursue a career as a physician-scientist. She is interested in tissue-specific drivers of inflammation in multi-organ system inflammatory disease. Most of all, she is excited to take care of our incredible patients and to have the privilege of being part of their journey! When not in the hospital or in the lab, she is an avid runner, enjoys all things outdoors (with a predilection for Nordic pursuits like cross country skiing), learning new skills (guitar, raised bed gardening), and spending time with friends and family.  She is blissfully unaware of her Canadian accent and quintessentially loves maple syrup.

Brittney Newby, MD, PhD: Brittney is a first-year rheumatology fellow.  Originally from Atlanta, she completed her undergrad studies at FAMU before pursuing her MD-PhD at the University of Florida. Her thesis focused on unraveling the diabetogenic potential of Type 1 Interferon in Type 1 Diabetes. Following medical school, she completed her residency and a chief year at CHOP, where she discovered her true clinical passion in Rheumatology. Brittney is particularly intrigued by the interplay between environmental factors and the shaping of the immunological landscape, leading to autoinflammation, autoimmunity and immune dysregulation. She aims to contribute valuable insights to this dynamic field to enhance the lives of her patients.

Outside of her professional pursuits, Brittney finds joy in spending quality time with her friends and family.  Some of her favorite pastimes include softball, roller skating, reading, and traveling.  Additionally, she indulges her passion for R&B and Soul music by attending concerts whenever her schedule allows, embracing the artistic and creative aspects of life. 

Research opportunities

Four members of CHOP Rheumatology research team Four members of CHOP Rheumatology research team Both clinical research and basic science research tracks are available to the fellow. The fellow is expected to lead a research project, of either a clinical or basic science nature, during the last two years of the fellowship program.

Other requirements

To carry out its mission, it is of critical importance for the Children’s Hospital of Philadelphia (CHOP) to keep our patients, families and workforce safe and healthy and to support the health of our global community. In keeping with this, CHOP has mandated all workforce members (including trainees) on site at any CHOP location for any portion of their time be vaccinated for COVID-19 as a condition of employment.

This mandate also applies to workforce members or trainees performing work for CHOP at non-CHOP locations. Additionally, all workforce members based in or regularly scheduled to work at any New Jersey location are mandated to be both vaccinated and boosted for COVID-19, with booster timing consistent with applicable guidelines. The CHOP COVID-19 vaccine mandate is in alignment with applicable local, state and federal mandates. CHOP also requires all workforce members and trainees who work in patient care buildings or who provide patient care to receive an annual influenza vaccine. Employees may request exemption consideration for CHOP vaccine requirements for valid religious and medical reasons. Please note start dates may be delayed until candidates are fully immunized or valid exemption requests are reviewed. In addition, candidates other than those in positions with regularly scheduled hours in New Jersey, must attest to not using tobacco products.

Children's Hospital of Philadelphia is an equal opportunity employer. We do not discriminate on the basis of race, color, gender, gender identity, sexual orientation, age, religion, national or ethnic origin, disability, protected veteran status or any other protected category. CHOP is a VEVRAA Federal Contractor seeking priority referrals for protected veterans.

CHOP is committed to building an inclusive culture where employees feel a sense of belonging, connection, and community within their workplace. We are a team dedicated to fostering an environment that allows for all to be their authentic selves. We are focused on attracting, cultivating, and retaining diverse talent who can help us deliver on our mission to be a world leader in the advancement of healthcare for children.

We strongly encourage all candidates of diverse backgrounds and lived experiences to apply.
