Biography

Maria Siemionow (Jenny Fontaine/UIC)

Dr. Maria Siemionow is an expert on vascularized composite allografts, hand surgery,  peripheral nerve surgery and microsurgery.

In 2008, Siemionow led the team of surgeons that performed the first near-total face transplant in the United States at the Cleveland Clinic. At UIC, her clinical focus is on hand surgery and peripheral nerve surgery.

Her research is aimed at reducing allograft rejection and the need for lifelong immunosuppressive drugs in transplant patients and developing new techniques to enhance nerve regeneration. She is investigating the effect of chimeric cells — made by fusing donor and recipient bone marrow stem cells — on the immune system’s natural attack response to foreign tissues and donor organs.

She recently used this technique to develop cells for treatment of Duchenne muscular dystrophy, a rare and fatal genetic disorder for which there is currently no cure. She advanced this technology into first-in-human clinical studies, demonstrating its broad translational potential across transplantation and regenerative medicine. For this groundbreaking contribution, she was honored with the 2025 UIC Inventor of the Year Award.

Her work on repairing nerve damage revolves around the innovative use of epineural sheaths. The epineurium is a layer of tissue that surrounds, nourishes and protects bundles of nerves and enhances nerve regeneration.

She is a member of the academic-industry team known as the Warrior Restoration Consortium, which focuses on the development of clinical therapies and new treatments for wounded soldiers as part of the second phase of the Armed Forces Institute for Regenerative Medicine.
