Dr. Yingxin Gao began her engineering education at the Huazhong University of Science and Technology, receiving a Bachelor of Science degree in 1999 in the dual majors of Power Engineering and Economics. She received her Master of Science in Mechanical Engineering from the University of Delaware in 2003, then earned a Ph.D. in Mechanical Engineering at the University of Michigan, Ann Arbor in 2007. Following completion of the Ph.D. Dr. Gao held a postdoctoral position with the University of Michigan before moving east to accept a position as Visiting Scientist with The Hospital for Special Surgery, Biomechanics and Biomaterials Laboratory in New York City from January 2008 to present. She subsequently began in her present position as Assistant Professor in Mechanical Engineering at Cornell in July 2008.

Research Interests

Dr Gao's research is focused on using mechanical theory to understand mechanical behavior of skeletal muscle and determine the effects of muscle degeneration on joint stability, with clinical applications on diagnosing and monitoring muscle degeneration induced by injury, aging and disease, and helping making clinical decisions on joint replacement. Specifically, Dr. Gao is interested in: (1) determining the mechanisms lateral transmission of force in skeletal muscle, how this transmission mechanisms affect the passive and active mechanical properties of skeletal muscle, and its role on preventing muscle injury; (2) using ultrasound images and ultrasound elastography to characterize architecture and mechanical properties of muscle, which will be then further used to identify the normal and degenerated muscles; (3) investigating the effects of deficiency of rotator cuff muscle, the main mechanisms for shoulder stability, on contact mechanics and kinematics of normal shoulder joint and/or total shoulder replacement; (4) skeletal muscle tissue engineering with application in Hernia and Pelvic Floor Prolapse.

Teaching Interests

Dr. Gao's teaching is focused on solid mechanics and bio-solid mechanics of musculoskeletal tissues.

Service Interests

Dr. Gao's service is focused on department service, and are currently the undergraduate program committee member, and freshmen adviser.
