As early as in college, Dr. Chang Yi Wang studied at Rockefeller University with a full scholarship and obtained a doctorate in immunology and biochemistry. During his stay at Rockefeller University, inspired by many Nobel Prize winners, in the early 1970s, when immunology was still unclear, President Wang put forward the idea of combining chemistry with immunology, and resolutely devoted himself to immunology research with the belief that immunology was a secret weapon of medicine. After receiving his doctor's degree, Chairman Wang immediately joined the Memorial Si Long-Kettering Cancer Center as the director and project host of molecular immunology laboratory, and his experience in leading the laboratory became an important reference for him to run the company in the future.

Dr. Wang founded UBI in Long Island, new york from 65438 to 0985. At the beginning of its establishment, it was invested by Olympus Company of Japan to assist UBI in developing various blood diagnostic reagents. Dr. Wang's knowledge of molecular immunology is superb. Under his leadership, UBI became famous in the field of international biomedical diagnosis, vaccine and immunotherapy with the specialty of "designing peptides" in the 1990s.
