Although he knew little about photonics before graduate school, he was drawn to optics, lasers, and spectroscopy from the beginning. He first caught a glimpse of what photonics could enable while working in Prof. Randall Goldsmith’s lab, where he became captivated by the idea that light could be guided, confined, and manipulated in unexpected ways. He later ventured deeper into the nanoscale world in Prof. Jen Dionne's lab at Stanford, where he became fascinated by how carefully designed structures can “trick” light and shape light–matter interactions in powerful ways. Outside the lab, Feng enjoys hiking, running, century-mile cycling, and doing fun chemistry experiments at home with his two boys.
