Marshall Zhang had dreamed of one day working in the field of science, but after discovering a new combination of drugs that could possibly be used to as a treatment for cystic fibrosis, the 16-year-old Richmond Hill student says he has gained a new perspective of the field. “Until recently, I’ve known the disease from a scientific point of view,” said Zhang, a Grade 11 student at Bayview Secondary School. “But knowing the facts is not the same as talking to people with diseases.” Cystic fibrosis is a debilitating and potentially fatal condition that causes thick mucus to build up in the lungs, making it difficult to breathe. The discovery lead him to first place at the 2011 Sanofi-Aventis BioTalent Challenge, a competition where student compete with the help of a mentor.
