Professor Yazhu Chen is a Member of Chinese Academy of Engineering and Professor of Biomedical Engineering, who is a world renowned authority in biomedical engineering and high voltage technology. She graduated from SJTU. During her early career, she conducted research in the field of high voltage technology, over-high voltage protection and numerical computation of static electrical field for high voltage systems. During early 1980s, she led the research and development of non-invasive treatment of kidney stones, and has become one of the pioneers in the interdisciplinary research on medicine and engineering. Her team successfully developed extracorporeal shock wave lithotripsy in 1985, which was granted the First Prize of National Science and Technology Advancement Award in 1987. This innovative technology has been used successfully to treat millions of kidney stone patients, which has generated great economical and social benefits. Since late 1990s, Professor Chen's work has focused on the development and clinical applications of physical therapy technology for tumor, which have led to several major achievements in the field of therapeutic ultrasound. She was the first to propose the concept of integrated modalities for tumor treatment. Integrated modalities for tumor treatment is a multimodality therapy that combines phased array high-intensity focused ultrasound with chemotherapy and radiotherapy. This concept has been widely recognized by her peers. Professor Chen has had over 300 research papers published, and over 30 invention patents approved by Chinese Patent Office.
