About our Fellowship Program
Welcome to the Stanford Pulmonary, Allergy and Critical Care Medicine Fellowship. We offer a 3-year ACGME accredited fellowship designed to provide outstanding clinical and research training in an intellectually vibrant and highly supportive learning environment. Our fellowship’s four distinct tracks are structured to offer trainees experiences that align with their unique career goals. We also offer an additional 4th year of subspecialty training in Lung Transplantation, Pulmonary Hypertension and Sleep Medicine which fellows can apply for in their third year.
Training
All fellows receive 18-20 months of clinical training in Pulmonary & Critical Care Medicine with core rotations at Stanford University Hospital, the Santa Clara Valley Medical Center, and the Palo Alto VA Health Care System. By rotating at these hospitals with distinct patient populations, fellows are exposed to a wide breadth of disease states and pathology. Our elective courses provide the opportunity for the additional in-depth study of specific areas of interest. Our fellows are also provided ample time to explore outstanding research opportunities at Stanford. Thank you for your interest in our fellowship program and for exploring our website. Please don't hesitate to contact us for further information.

The PACCM division congratulates Dr. Raquel Lyn, recipient of the Team Science Award from the Department of Medicine to study the impact of race and ethnicity in pulmonary arterial hypertension (PAH) for patients exposed to methamphetamine. PAH is a rare and fatal disease often affecting young women. Methamphetamine associated PAH (Meth-APAH) is a subtype of the disease with rising prevalence in disadvantaged populations. While recent studies have characterized Meth-APAH's clinical phenotype and outcomes, no studies to date have evaluated impact of such social drivers of health in Meth-APAH. In her proposal, Raquel will seek to evaluate the impact of race/ethnicity in patients with longstanding history of methamphetamine use, focusing on determinants of health disparities in under-represented minorities.
Dr. Lyn will use the NIH infrastructure provided by Drs. Roham Zamanian and Steven Kawut (University of Pennsylvania) to evaluate the prevalence, attitudes, patterns, and impact of substance abuse in under-represented minorities using a novel PH substance use questionnaire.

The PACCM division congratulates Dr. Matthew McCarra, who has been selected as this year's recipient of the 2025 Stanford Cancer Institute (SCI) Fellowship Award! The fellowship is part of the Stanford Cancer Institute's commitment to nurturing the next generation of cancer researchers. This funding is awarded to researchers engaged in basic or translational cancer research, with a focus on projects that advance understanding or treatment of cancer. The program provides vital support to enable promising researchers to secure future faculty positions and career development awards.
Working in the laboratory of Dr. Tushar Desai, Matt's research focuses on lung epithelial and stem cell biology, specifically the role of telomerase-expressing alveolar type 2 (AT2) cells in lung regeneration and cancer. He has discovered a novel population of TERT expressing AT2 cells that act as unipotent progenitors important for lung homeostasis and injury repair. Notably, these cells exhibit a unique regulatory mechanism, producing smaller tumors when driven by mutant Kras, compared to other AT2 stem cells. Through sequencing and chromatin studies, he aims to unravel key molecular distinctions that may explain their differential tumorigenic potential and identify markers for human lung studies. This work aims to advance understanding of lung cancer and stem cell biology and pave the way for targeted therapies.

Please join the PACCM division in congratulating Drs. Lauren Eggert and Gaurav Singh in their new roles as Associate Program Directors for the Pulmonary & Critical Care Fellowship! Lauren and Gaurav are emerging leaders in our field and have been lauded for their many contributions to medical education at Stanford and beyond. We are delighted to have them step into this important leadership role within our Division where they will continue to foster academic excellence in our trainees. They will be joining Joe, Andrea, and Angela in the ongoing important work of recruiting, training, and shaping careers for the future leaders in PCCM academic medicine.
Dr. Gaurav Singh completed his MD at the University of California San Francisco and his internal medicine residency at Stanford University. He completed a Master of Public Health at UC Berkeley and then returned to Stanford to complete fellowship training in both pulmonary and critical care as well as sleep medicine. Gaurav joined the Stanford faculty before he was recruited to the VA Palo Alto in 2018, where he has served as a PCCM Fellowship Site Director. Gaurav has been instrumental in the development of the AIRE Sleep Training Program within our fellowship and has served as a mentor and educator to many of our fellows through his many clinical and educational responsibilities at the VA. His superlative teaching was recognized when he was the 2018 recipient of the PCCM Division Teaching Award. He has authored multiple systemic reviews and is regarded as a leader in the intersection of sleep medicine and critical care. Gaurav's impact has been significant at a national level: he was recently elected as the California Thoracic Society Treasurer and serves as a leader in the VA Sierra Pacific Network overseeing pulmonary care throughout the Pacific Coast and Islands. We are delighted to have him joining the Stanford PCCM Fellowship Leadership where he will continue to expand on the clinical and educational offerings for fellows at our multiple affiliated sites.
Dr. Lauren Eggert completed her MD at Albert Einstein College of Medicine before her residency training at Icahn School of Medicine at Mt Sinai. She completed her Pulmonary & Critical Care Fellowship at Stanford. Since joining the faculty here in 2020, she has emerged as a leader in severe airways disease and is the Director of the Airways Disease Program. She has authored multiple pieces establishing her expertise in biologics, severe airway disease management, and ABPA. Lauren serves as the pulmonary representative for the SHC Value Based Care initiative and has overseen multiple QI initiatives including modernizing PFT interpretation, expanding pulmonary rehab access, and decreasing ED utilization among patients. Her impact has been seen at both the regional and national levels: she serves as a co-chair of the CTS annual conference and runs the Apprenticeship program for the ATS Early Career Working Group AII assembly. She serves on the ATS AII program committee and post-graduate course selection committee. She has experience with curriculum development and developing early-career physicians. We are delighted that Lauren will bring these tremendous skills to the Stanford PCCM fellowship program. She will be leading the growth of our outpatient pulmonary curriculum and expanding fellow education and mentorship efforts around quality improvement.
Please join us in congratulating these two very accomplished physicians as they embark on this exciting next chapter in their careers!

A big congratulations to Dr. Jyothi Tirumalsetty from our talented PACCM Adult Allergy team who has published a landmark study with collaborators today in JAMA.
The article examines the greenhouse gas emissions and costs of medical inhalers on the US market. The work is the result of a collaboration between colleagues at the Stanford University, University of Michigan, and the National Health Service of England. They take stock of the US inhaler market, calculate how much inhalers contribute to healthcare system emissions, and compare emissions and costs between metered-dose inhalers and their less-polluting cousins, dry-powder and soft-mist inhalers. They describe how less environmentally damaging inhalers are disproportionately more expensive in the US, making an ecological transition challenging. The authors are hopeful that this work will spur further discussion about the importance of reducing the global warming effect of inhaled medications. But more broadly, the article speaks to the trade-offs required within healthcare to weigh clinical efficacy vs. environmental impact vs. cost.

We are pleased to announce that Dr. Meghan Ramsey has been named the Associate Chief of Strategy and Development for the division.
Meghan's dedication to the division and her professionalism is well recognized. She graduated from Stanford Medical School, completing both her internal medicine residency and PCCM fellowship here. She served as chief resident and chief fellow respectively. She joined the PACCM faculty in 2015, with a career focus and clinical interests in critical care medicine and education.
During the early phase of her career at Stanford, she joined our interventional pulmonology group and trained in advance bronchoscopies and lung cancer management. One year later, the division expanded our presence at the Tri-Valley (TV) ICU (then named ValleyCare), and she was the first PACCM faculty member who traveled to the East Bay, often spending nights and entire weekends there to help our patients there. She was instrumental in the strategy and operation for TV-ICU when it expanded to 24/7/365 coverage. Her work enables the division to grow with recruitment of more than 16 new faculty since 2017. Meghan was named the interim medical director in 2021 and the position was changed to being permanent in 2022.
Meghan became the IM-CCM fellowship Program Director in 2021, and began working alongside Dr. June Gordon, Associate Program Director of the fellowship. Together, they fostered an excellent culture, improved education, and expanded operational scope.
Nationally, Meghan has contributed significantly to the American College of Chest Physicians. She participates often in educational workshops for PCCM nationwide and is a valued member of the foundation.
Last year, our division expanded further to Good Samaritan Hospital ICU with 44 beds. Meghan provided a central role in the programmatic planning for more than 12 community ICU physicians and faculty working together in a critical location in the South Bay to provide complex care. Her work and the important partnership with SHC administrative leaders, allows Stanford Medicine to be integrated into communities and at the same time provides a needed mechanism to recruit talented faculty for our division to continue its growth for years to come.
All of these activities revealed Meghan's significant talent for talent and program development. She is a well-respected physician-leader in the division, department, and the hospital.
Please join us in congratulating Meghan on this important new role.
Sincerely,
Dr. Mark Nicolls, Dr. Arthur Sung, and Benita Kaeding
