Aus Bio Ltd. Researcher Wen-Yang Wu

Wen-Yang Wu, executive director of research and development at Aus Bio Ltd., poses for a photograph at the company's laboratory in Melbourne, Australia, on Tuesday, Feb. 6, 2018. Wu, who helped discover GlaxoSmithKline Plc's flu drug Relenza, is developing a novel way of preventing flu viruses from infecting respiratory cells. It works by reshaping the hemagglutinin, another protein on the surface of the virus, by creating a low pH environment that mimics the change that occurs after a virus invades a host cell, Wu said.
