Jang -Hwan Choi, Ph.D.

Jang-Hwan Choi has obtained a Ph.D. in January 2015 from Stanford University (Palo Alto, USA) on “C-arm CT-based weight-bearing CT development”. Then, in 2015, he developed a diagnosis and treatment technique for knee diseases (osteoarthritis, patellofemoral syndrome) caused by mechanical causes using weight-bearing CT and musculoskeletal modeling during his postdoctoral fellowship at Stanford medical school. Based on these findings, he has been awarded the New Investigator Recognition Award by Orthopedic Research Society, the most prestigious international society for orthopedic research. In 2016, he served as a senior researcher at the Electronics and Telecommunications Research Institute. In March 2017, he was appointed as an assistant professor at the division of mechanical and biomedical engineering at Ewha Womans University. He heads the division and the Artificial Intelligence-driven Biomedical Imaging (AIBI) lab. Currently, his lab conducts research on the development of technologies for diagnosis / treatment of lesions and related medical devices by using machine learning / artificial intelligence, medical big data, X-ray based next generation medical imaging system at Ewha Womans University.
