Yuxin Qian is a Ph.D. candidate at Nanjing Medical University under the mentorship of Prof. Lei Jin. Her research focuses on the development of biomaterial-based therapies for radiation-induced tissue injuries, particularly oral mucositis. She has published in peer-reviewed journals on biomaterials for oral tissue repair, and immunomodulation strategies. Her current work integrates engineered exosomes, CAR-macrophages, and microneedle delivery systems to provide novel therapeutic approaches for translational medicine.
