My name is Qing-Jian Li, and I graduated from Sun Yat-sen University with my PhD in 2020. As a physician in the Department of Medical Oncology at Sun Yat-sen Memorial Hospital, I am currently serving as an associate researcher and master's supervisor at Sun Yat-sen university. I specialize in medical treatment of tumor, especially in the diagnosis and treatment of breast cancer, lung cancer, liver cancer, nasopharyngeal cancer, and other common tumors. My research focus is on the mechanisms of breast cancer metastasis and therapeutic resistance, as well as the clinical translation of nanomedicines. Relevant research outcomes have been published in "Nature Communications," "Advanced Science," "Cancer Research," and "Nature Biotechnology". I have co-authored and served as the corresponding author for more than 10 publications, with the most cited paper garnering 134 citations. Currently, I am a reviewer for Frontiers in Molecular Biosciences and have reviewed more than 10 manuscripts in total. As a physician and researcher, my personal and professional goals focus on several key areas. I am committed to enhancing clinical diagnosis and treatment precision through continuous learning and practice, providing patients with higher quality medical services. I conduct in-depth research on tumor metastasis and therapeutic resistance mechanisms to explore new treatment targets and methods to improve patient outcomes. I also look forward to collaborating with experts from various fields, integrating knowledge from biology, materials science, engineering, and more, to foster innovation and development in medical research. Additionally, I aim to share my research findings and experiences by publishing papers, attending academic conferences, and mentoring students, promoting academic exchange and knowledge dissemination. As a physician and researcher, I attentively listen to the needs of patients and colleagues to ensure accurate understanding and appropriate responses. I effectively communicate complex medical information and research findings, ensuring accurate information transfer. I also maintain good relationships with patients, families, and medical teams to foster collaboration and trust. I have mentored 3 medical students, 1 resident, and 2 researchers while managing 2 research grants. I creatively solve clinical challenges and research issues. I enjoy playing basketball and am a member of the college team.
