Steve holds a PhD in Medical Biochemistry from the University of Toronto, Canada. He worked as a medical scientist in both industry and academia for two decades, with a focus on the design of new medicines for infectious diseases and immune-related disorders. In 2019, Steve joined Bionews as a science writer to help make the latest medical research more accessible for everyone.
