Her work is well-funded by the NIH and industry, resulting in over 130 publications and several book chapters. Dr. Li is the Director of the Program for Advanced Medical Imaging and inaugural Bonutti Family Endowed Chair at the Cleveland Clinic.

She was recently elected to the 2019 American Institute for Medical and Biological Engineering College of Fellows, Before being recruited to Cleveland Clinic in 2017, Dr. Li was a Professor in the Department of Radiology and Biomedical Imaging at the UCSF. She earned her BS from Tsinghua University, China, and her PhD in bioengineering from UC Berkeley and UCSF.

J. Lawrence Marsh, MD

J. Lawrence Marsh, MD, is the Chairman of the Department of Orthopedics and Rehabilitation. His clinical expertise encompasses a wide variety of fractures, bone infections, and post-fracture problems such as failure to heal and post-traumatic arthritis.

He has a variety of research interests in the assessment and treatment of fractures with emphasis on minimally invasive techniques, post-traumatic arthritis and fracture classification.

He was the president of the American Board of Orthopedic Surgery from 2015 to 2016 and completed his 10-year commitment with the board in the Fall of 2019. He was the president of the American Orthopedic Association and the Mid-America Orthopedic Association from 2014 to 2015.

Dr. Pietrosimone’s research seeks to decrease disability related to knee injury with a focus on maximizing long-term joint health following traumatic joint injury.  Much of his research has evaluated the neuromuscular mechanisms related to disability following lower-extremity joint injury. Additionally, he has sought to develop novel intervention strategies to treat neuromuscular impairments and improve clinical outcomes.  His future projects look to evaluate how measures of joint metabolism interact with early biomechanical changes following traumatic knee injury for the purpose of minimizing the risk of posttraumatic osteoarthritis development.

Jeffrey Spang, MD
