MEET THE SURGEONS

Our Team

Dr. Dumanian will lead the courses, and will be ably assisted in teaching and performance of surgery by Drs. Jason Ko and Sumanas Jordan. We expect to have guest faculty for each lecture to add to the experiences learned at Northwestern.

Dr. Gregory Dumanian

Dr. Gregory Dumanian

Dr. Gregory Dumanian is Chief of Plastic Surgery at Northwestern. Trained at the University of Pittsburgh, he was an early adopter of components separation hernia repairs, and described “perforator preservation techniques” back in 2002 to decrease wound-healing complications associated with the procedure. He has developed a novel mesh suture for internal high-tension closures, including for the abdominal wall.

Dr. Dumanian is also the developer of Targeted Muscle Reinnervation, a peripheral nerve procedure designed for improved prosthetic control in amputees. He has worked extensively for the last 15 years with both plastic surgery and orthopedics at the Walter Reed National Military Medical Center Department of Surgery to refine and develop this surgery that shows great promise in the treatment of the pain and phantoms of wounded warriors.

Jason Hyunsuk Ko, MD

Dr. Jason Ko is an Associate Professor of Plastic Surgery, with a dual appointment in the Department of Orthopaedic Surgery, at Northwestern University Feinberg School of Medicine.  Dr. Ko completed the Integrated Plastic Surgery Residency at Northwestern University, where Dr. Dumanian was the Program Director and Chief.  During his time at Northwestern, Dr. Ko performed a large number of Targeted Muscle Reinnervation (TMR) procedures under the guidance of Dr. Dumanian and received a Plastic Surgery Foundation (PSF) fellowship for his research on the effects of TMR on neuroma formation.  Dr. Ko then did a fellowship in Hand and Microvascular Surgery at the University of Washington in Seattle, WA, and he then joined the faculty at the University of Washington, where he primarily practiced at Harborview Medical Center, performing a high volume of TMR procedures, while also focusing on brachial plexus and peripheral nerve reconstruction, hand and upper extremity surgery, and microvascular reconstruction.  Dr. Ko was recruited back to Northwestern in 2016 and is now the Program Director for the plastic surgery residency program.  Dr. Ko was the Co-PI of a US Dept. of Defense (DoD)-funded prospective clinical trial (PI: Dumanian) comparing the efficacy of TMR for the treatment of neuromas in upper and lower extremity amputees, which will help TMR become the gold standard treatment for the prevention and treatment of nerve pain in amputees.

Dr. Sumanas Jordan

Dr. Sumanas Jordan

Dr. Sumanas (Sue) Jordan is an Assistant Professor of Plastic Surgery at Northwestern University Feinberg School of Medicine. She received her MD/PhD in Biomedical Engineering from Emory and the Georgia Institute of Technology in 2010. She completed her thesis on bioinspired surface modification of vascular grafts and finite element modeling of blood coagulation. Dr. Jordan is a graduate of the integrated plastic surgery residency program at Northwestern University under Dr. Gregory Dumanian. She completed a reconstructive microsurgery fellowship at The Ohio State University, during which she coordinated a number of multicenter research studies (Northwestern, OSU, Walter Reed, MGH) on targeted muscle reinnervation for the treatment and prevention of postamputation pain with Dr. Ian Valerio. Dr. Jordan has published on topics ranging from biomaterials to breast reconstruction and TMR, in journals including Science Translational Medicine, Advanced Functional Materials, Plastic & Reconstructive Surgery, and Annals of Surgery. Her clinical focus includes targeted muscle reinnervation, microsurgery for lymphedema, and gender affirmation surgery. In her laboratory, she is developing bioactive, 3D-printed scaffolds for skeletal muscle and peripheral nerve regeneration.
