During medical school, she was selected to perform translational research at the National Institutes of Health through the Medical Scholars Research Program. She subsequently completed her residency training in otolaryngology-head and neck surgery at Boston University’s Boston Medical Center, and her fellowship in pediatric otolaryngology at the Children’s Hospital of Wisconsin in Milwaukee. Dr. Jang is a member of the American Academy of Otolaryngology-Head and Neck Surgery and is Board Certified in Otolaryngology. She is the author or co-author of several journal articles and textbook chapters, and regularly presents her research at national meetings.

Dr. Katherine Rosenwasser is the Chief of Pediatric Orthopedic Trauma at Columbia University Irving Medical Center (CUIMC) / Morgan Stanley Children's Hospital of New York (MSCHONY). She is an expert in the operative and non-operative treatment of lower extremity deformity and musculoskeletal trauma in pediatric patients – from infants to adolescents. Her practice focuses on caring for children with limb-length discrepancies, clubfoot, congenital deformities, and those requiring complex lower extremity reconstructive surgeries. Dr. Rosenwasser’s advanced training allows her to leverage the latest surgical techniques and non-operative therapies to provide life-altering interventions for young patients. After receiving her medical degree from Columbia University’s Vagelos College of Physicians & Surgeons, Dr. Rosenwasser remained at Columbia University Irving Medical Center and NewYork-Presbyterian where she completed residency training in orthopedic surgery, serving as executive chief resident. Following her residency, Dr. Rosenwasser completed dual fellowships in pediatric orthopedic surgery at the Hospital for Sick Children in Toronto, and pediatric limb lengthening and reconstruction under the direction of Dr. John Herzenberg at the Sinai Hospital’s Ruben Institute for Advanced Orthopedics in Baltimore, Maryland. Dr. Rosenwasser is an active member of the academic orthopedic community, both as a member of numerous national organizations and as an active researcher with a variety of ongoing research projects focused on improving patient outcomes for children who require complex orthopedic care.

I am a pediatric endocrinologist with interests that include polycysytic ovary syndrome (PCOS), bone health, disorders of puberty, thyroid disorders, pituitary disorders and growth disorders. In addition to my training in pediatrics and pediatric endocrinology, I have Master of Science degrees in Nutrition (1999) and in Patient Oriented Research (2014) and have completed a research fellowship at the Body Composition Unit of Columbia University Medical Center (2003). I comleted the TRANSFORM KL2 program sponsored by the Irving Institute of Clinical and Translational Research, a mentored career development program. My responsibilites include my clinical practice, overseeing clinical and research fellows, mentoring students, and running a clinical study. I have been certified as a clinical densitometrist by the International Society of Clinical Densitometry and interpret pediatric bone mineral density studies performed at Columbia University Irving Medical Center. My research project, “A double-blind placebo-controlled randomized clinical trial assessing the efficacy of metformin for hepatic fat in adolescents and young adults with polycystic ovary syndrome” has the primary goal of exploring the use of novel and noninvasive testing and a pilot double-blind placebo-controlled trial of metformin with the intention of identifying and potentially treating non-alcoholic fatty liver disease in adolescents and young adults with PCOS. My research is unique in that it uses minimally invasive body composition methodology, which makes it particularly attractive for use in adolescents and young adults. My overall clinical research goal is early identification and treatment of metabolic and body composition abnormalities associated with PCOS and to prevent lifelong morbidity associated with this disorder in a young population
