Fellowship was truly my favorite part of training. The vision and culture here are exceptional—kind, collegial, and deeply supportive. The environment is warm and open, and the faculty genuinely prioritize fellow education and learning. One of the things I appreciated most was how the attendings not only supported fellows, but also each other—there’s a real sense of teamwork, especially when tackling tough or complex cases.
I absolutely loved our case conferences—which, let’s just say, could get a little spicy in the best way! They were engaging, thought-provoking, and such a valuable learning experience.
The children’s hospital offers an incredible breadth of pathology, with particularly strong exposure to transplant and immunocompromised patients—Pittsburgh really is the transplant capital of the world. There’s a strong emphasis on autonomy, and the tenure program and division structure are both phenomenal. If I had to do fellowship all over again, I would choose this program without hesitation.

I loved my fellowship years at the Children's Hospital of Pittsburgh and am so grateful for the heartfelt, longitudinal mentorship I received (and continue to receive)! The faculty is deeply collegial and wise - they are always willing to think profoundly about cases together and passionately share their mental models!
Every week, there are multiple venues for growing academically and honing clinical skills; the educational curriculum is vibrant and includes weekly formal sign-outs where many faculty join to provide input for cases, invigorating weekly case conferences where members of the division walk through how they process clinical scenarios, dedicated pediatric ID fellows’ curriculum 3 times a month (everyone, including fellows, rotates in hosting lectures), and journal clubs 2x/month. We also get to lead ID grand rounds once a year.
The faculty are experts and leaders in their sub-specialties and are excited to invite fellows to participate in national/international committees and projects. While at UPMC, I worked with the International Pediatric Transplant Association and American Society of Transplantation in significant ways under the supportive mentorship of the transplant ID faculty - these experiences have continued to shape my career profoundly!
During my time at UPMC, Bone Marrow Transplant and Allergy & Immunologyattendings also took me under their wings, allowed me to work with them in their clinicand on scholarly projects, and they continue to provide counsel and mentorship today. I very much love all my UPMC mentors - if you are reading this, thank you! I hope you know how much you mean to me :) I have enjoyed working with you and listening to your accumulated wisdom during my fellowship and beyond.

Graduated 2023 (Pediatric Scientist Development Program Track)
When I graduated from Temple University School of Medicine, I interviewed at several of the Top 10 Pediatrics Hospitals, and UPMC Children's Hospital of Pittsburgh stood out as a fantastic place to complete my residency training. The collegial environment of the hospital combined, superb teaching, and diverse patients combined with a smaller city that has a ton of big city amenities was a great fit for me. The Pediatric Scientist Development Program at Children's added even more fuel to my fire to train. I knew that with a program like the PedSDP at the institution there was an emphasis on research and scientific discovery. When it came time to decide on my fellowship program, I couldn't have imagined going anywhere else because of my experience with the infectious diseases team during my residency. The ID division is truly superb in their teaching, research, and experience. There are pioneers in the field of transplant infectious disease as well as stellar scientists in virology and bacteriology. While the clinical faculty are spectacular, the connections with University of Pittsburgh researchers gave me the opportunity to pursue the research in the field of my desires with a great mentor. I couldn't be happier with my decision, and I think that decision has set me on a path to achieve all my career goals.

Graduated 2022 (Pediatric Scientist Development Program, Accelerated Research Pathway)
I had never been to Pittsburgh prior to interviewing for residency, but I immediately felt “at home” and like I’d found my people. The residents didn’t take themselves too seriously, but ended up being incredibly thoughtful and intelligent doctors and I’m so lucky that I got to learn from them. I’d hoped to find a location that I could stay for both residency and fellowship, and was specifically interested in the “Accelerated Research Pathway,” a program through the ABP that allows research-focused residents the opportunity to do two years of residency and an extended four year fellowship so that they can spend some extra time doing research. Children's had just started the Pediatric Scientist Development Program that encouraged just that. Not only would I be able to do the research pathway, but I would have a cohort of others along the way! The icing on the cake is getting to be a part of our Pediatric Infectious Diseases Division. They are leaders in the field, including in Transplant infectious diseases, and I have plenty of role models for successful physician-scientists. The program has been nothing but supportive of my individual development and career goals, even when it caused some major clinical scheduling challenges during my dedicated research years. I can’t imagine training anywhere else!

2019-2020 (Combined Infectious Diseases/Pediatric Critical Care Fellowship)
I actually came to Children's from Lurie Children’s as a PICU fellow, although I had completed a year of ID fellowship at Lurie prior to coming here. This was because my wife still had a year of training left when I finished residency, and when considering subspecialties in residency, I was deciding between critical care and infectious diseases. When there was an open spot in the ID fellowship for my “gap” year, I jumped at the opportunity to fill the role, knowing how much I would learn along the way. I subsequently chose Pittsburgh based on the breadth of patients we see here, including a very large transplant population, and the strong research foundation they have. Over time, I got to know the ID division as they welcomed me to their case conferences, which were always filled with interesting cases (many from the PICU). I realized early on that they would be a great group to work with and learn from, and towards the end of my PICU fellowship, we were able to work out my finishing ID fellowship here as well. Ling Lin, the fellowship director, in particular went to great lengths to work things out with the ABP and make sure it went smoothly, even though I wasn’t even her fellow yet. That’s just one example of how invested the division as a whole is in the success of its fellows though. As for Pittsburgh, it has an amazing ability to grow on you. I thought I’d be here for 3 years and leave, and here I am 4 years later having just started as faculty in both ID and critical care.

Graduated 2020
I came to UPMC Children’s Hospital of Pittsburgh from the University of California – San Diego for residency, and stayed for a year as Chief Resident and then for my Pediatric Infectious Diseases fellowship. Children's provides world-class clinical training – as the only major pediatric medical center in the region we take care of the most common medical complaints as well as the most complex and rare disorders in pediatrics. Our faculty are international leaders in many clinical and research fields, and Children's is a world-wide leader in pediatric transplantation, which was a huge benefit to my ID training. As fellows we work not only with the researchers in the Department of Pediatrics, but from throughout the University of Pittsburgh community. I work in Bioinformatics and Data Science and received direct mentorship from faculty in the Pitt Department of Biomedical Informatics, which helped me bridge the gap between my academic and clinical interests. Children's combines an unbeatable clinical and academic environment with one of the most family-friendly and livable cities in the US. If I were choosing my fellowship location all over again, I would choose Children's.
