Matthew J. Weintraub, MD

Medical School: Rutgers New Jersey Medical School
Undergraduate: Tulane University, BS in Engineering

Originally from Watchung, New Jersey, Matthew developed an early interest in building, problem-solving, and hands-on work, shaped by time spent learning practical skills alongside his grandfather. That foundation carried into his engineering training at Tulane, where he studied biomedical engineering and mathematics, and ultimately into orthopedic surgery, where he found a natural fit for his interest in technical precision, biomechanics, and restoring
function. At Rutgers, Matthew distinguished himself through exceptional academic performance, scholarship, and leadership. An Alpha Omega Alpha inductee ranked in the top 5% of his class, he completed a dedicated clinical pediatric orthopedic research year at Columbia under Drs. Michael Vitale and Christen Russo, where he led a large portfolio of prospective and multicenter studies while remaining active in clinic, conference, and the operating room. His scholarly productivity is remarkable, with 18 peer-reviewed publications, 18 additional manuscripts, 28 poster presentations, and 22 oral presentations, reflecting deep engagement in pediatric spine deformity, outcomes research, and orthopedic innovation. Just as impressive is the way Matthew works. He is widely recognized for his integrity, maturity, and unwavering commitment to his team, with a calm presence and level of preparation that consistently elevate those around him. Faculty and residents alike describe him as the rare trainee who is both exceptionally productive and an outstanding teammate.

Graduate:
Undergraduate: University of Winsconsin–Madison, BS in Microbiology

Henry developed a deep interest in the biological foundations of human structure and disease during his undergraduate training in microbiology at the University of Wisconsin–Madison. He went on to complete his PhD in molecular biology at Princeton University, where his work focused on extracellular matrix biology and its role in disease processes, including fibrosis, vascular dysfunction, and cancer progression. His transition into orthopedic surgery was driven by a desire to connect this scientific foundation with clinical care, particularly in restoring form and function through surgical intervention. This perspective has shaped his approach to both research and patient care, with a clear commitment to advancing the field through translational inquiry. At Rutgers, Henry has distinguished himself as both a clinician and physician-scientist. An Alpha Omega Alpha and Gold Humanism Honor Society member, he has remained deeply engaged in research, with five peer-reviewed publications, multiple additional manuscripts, ten poster presentations, three oral presentations, and a U.S. patent focused on novel methods for targeting fibrotic extracellular matrix. His work reflects a sustained commitment to innovation at the intersection of basic science and orthopedic application. Henry is recognized for his thoughtful approach, intellectual depth, and strong clinical instincts. He is consistently described as inquisitive, hardworking, and deeply invested in improving patient care, with an ability to integrate complex scientific and clinical perspectives. We are proud to welcome Henry to our six-year research track, where his dedication to scientific discovery and clinical excellence will add meaningful depth to our research and clinical training environment.
