After college, Perry Hystad took a trip to India and, while touring several large cities, noticed the vast clouds of exhaust from vehicles, smoke from factories, and soot from biomass-burning cook stoves. As he watched the rapid urban expansion all around him, Hystad remembers thinking: What effect does breathing such pollution day in and day out have upon these people’s health?
This question stuck with Hystad, and he soon developed a profound interest in environmental health. In 2013, Hystad completed his Ph.D. in his native Canada, studying the environmental risk factors for lung cancer [1, 2, 3]. Now, with the support of an NIH Director’s Early Independence Award, Hystad has launched his own lab at Oregon State University, Corvallis, to investigate further the health impacts of air pollution, which one recent analysis indicates may contribute to as many as several million deaths worldwide each year .
