Dr. Hirji has established a distinguished academic career in cardiac surgery, marked by a dedicated commitment to patient care, innovative research and leadership within the medical community. As an associate surgeon in the division of cardiac surgery at Brigham and Women's Hospital, Harvard Medical School since July 2025, he is responsible for overseeing patient care, ensuring multidisciplinary collaboration among intensivists, surgical teams and residents, and performing complex procedures such as valve replacements and heart bypass surgeries. He is respected and recognized for his daily and evening rounds, reflecting his dedication to comprehensive patient management in the context of heart surgery.

Prior to this role, Dr. Hirji served as cardiothoracic surgery chief resident physician at Brigham and Women's Hospital, Harvard Medical School from 2024 to 2025. In this capacity, he led various surgical teams, coordinated multidisciplinary care for critically ill patients and contributed to the training and mentorship of junior residents. His tenure as cardiothoracic surgery resident physician at the same institution from 2021 to 2024 provided him with advanced operative experience in valvular heart disease and aortic disease, areas in which he has developed significant academic and technical expertise.

From 2022 to 2023, Dr. Hirji was general surgery chief resident physician at Brigham and Women's Hospital, where he managed various surgical services and mentored several junior residents and medical students from Harvard Medical School. His earlier experience as a general surgery resident physician from 2015 to 2022 laid the foundation for his clinical acumen and technical proficiency across a broad spectrum of general surgical disciplines.

Between 2017 and 2020, Dr. Hirji held the position of Vicky and Joseph Safra research fellow in the division of cardiac surgery at Brigham and Women's Hospital, Harvard Medical School. During this period, he conducted pioneering research on transcatheter cardiac technologies and their application across diverse patient populations with cardiovascular disease. He was academically productive with a passion about fostering excellence within surgical teams and contributing to the field's ongoing evolution through research, with over 280 peer-reviewed publications in major, high-impact academic journals to date.

Dr. Hirji's early research career began as a medical student research fellow at Duke Clinical Research Institute from 2013 to 2015. There, he initially published approximately 30 papers in leading academic journals, including Journal of American Medical Association (JAMA), the Journal of the American College of Cardiology (JACC), Circulation and The Lancet. His work on acute heart attacks became foundational for subsequent studies in cardiology, with one paper ranking among the most cited in JAMA.

Throughout his career, Dr. Hirji has been actively involved in professional organizations. He served as president of the Thoracic Surgery Residents Association from 2024 to 2025 and maintains membership with the Massachusetts Medical Society, the Massachusetts Chapter of the American College of Surgeons and The Society of Thoracic Surgeons (STS) as a candidate member.

Dr. Hirji's educational journey is marked by perseverance and achievement against significant odds. Born in Dar es Salaam, Tanzania, into a family with limited resources, he became the first in his family to attend high school. After graduation in 2007, he earned a scholarship to study bioengineering at Massachusetts Institute of Technology in Cambridge, MA. Immersed in an environment rich with innovation, he developed an interest in the unique intersection of medicine, bioengineering and surgery.

Mentorship during his undergraduate years enabled Dr. Hirji to purse in medical training at Duke University School of Medicine in Durham, NC. During medical school, he later secured a fellowship at Duke Clinical Research Institute, where his curiosity in cardiology and cardiac surgery flourished alongside his academic pursuits. In 2019, Dr. Hirji earned a Master of Public Health in clinical effectiveness from Harvard T.H. Chan School of Public Health in Boston, MA. He also holds certifications in advanced cardiovascular life support and basic life support, underscoring his commitment to maintaining high standards of clinical competence. Most recently, he pursued additional coursework toward a Michael J. Davidson structural heart and endovascular surgical fellowship at Mass General Brigham.

His scholarly contributions are extensive, and place him among the Top 5% of cardiac surgeons. Notably, Dr. Hirji critically defined how transcatheter technologies should be utilized across age groups and clinical scenarios—a body of work that has influenced both practice guidelines and future research directions. His studies on reintervention outcomes have been published in major journals such as European Heart Journal and Circulation: Cardiovascular Interventions. A landmark paper published in JAMA Cardiology examined differences between 30-day and 90-day outcomes after cardiac interventions; this work prompted industry-wide discussions about optimal assessment periods for hospital performance. His work on examining reinterventions after transcatheter aortic valve replacement (TAVR explant) was novel, and one of the first reported studies in the literature that was published in JACC.

Dr. Hirji's publication record includes authorship or co-authorship on numerous influential articles, such as "Bridge to Long-Term Mechanical Circulatory Support with a Left Ventricular Assist Device: Novel Use of Transcatheter Aortic Valve Replacement" in The Annals of Thoracic Surgery and "Extent, Location, and Clinical Significance of Non-Infarct-Related Coronary Artery Disease Among Patients with ST-Elevation Myocardial Infarction" in JAMA, among others spanning topics from lung transplantation outcomes to innovations in remote diagnosis.

His civic engagement reflects a deep commitment to service beyond clinical practice. Dr. Hirji volunteers as a second opinion medical professional triaging cases within local communities and supports activities at his community mosque. He is also founder of a blind school in Tanzania—an initiative that underscores his dedication to expanding access to education for underserved populations.

Recognition for Dr. Hirji's achievements includes receiving the Maxwell Chamberlain Award from the STS, the C. Walton Lillihei Award from the American Association of Thoracic Surgery (AATS), the John Kirklin Award from the STS, and the Joseph Murray Resident Research Award from the Massachusetts Chapter of the American College of Surgeons. He was also awarded the Brigham and Women's Hospital Department of Surgery Class of 1963 Scholar Award for excellence in research contributions. Additionally, he has also received the James W. Brooks House Staff Scholarship Award from the Southern Thoracic Surgical Association, receiving the Poster Distinction Award at the World Transplant Congress, earning the Outstanding Medical Student Research Award from Duke Clinical Research Institute and being awarded the Summer Intern Scholarship by the American Association for Thoracic Surgery.

Dr. Hirji attributes his success to values instilled by his parents as well as his faith and an unwavering belief in positive intentions. He emphasizes that hard work, perseverance and doing the right thing will lead to success over time, regardless of one's background. He also believes that anything is possible, pointing to his own rise from humble beginnings to a thriving career as evidence that patience, the right mindset and persistence make achievement attainable.

In his personal life, Dr. Hirji enjoys spending time outdoors with his young daughter—an activity that reflects both his appreciation for family life and commitment to well-being outside the operating room. Looking ahead, he aims to become a hybrid surgeon capable of offering both traditional open procedures and minimally invasive options for patients requiring complex cardiac interventions. He is dedicated to remaining at the forefront of technological advancements while critically evaluating their impact on patient outcomes through an outcomes group focused on emerging technologies as they enter clinical practice.
