Jonghee Yoon SPIE's #FacesofPhotonics is sharing the story of Jonghee Yoon. Jonghee is a Research Associate at the University of Cambridge in Dr. Sarah Bohndiek’s VISIONLab. He is originally from South Korea, and his current research involves using hyperspectral imaging to identify and diagnosis oesophageal cancer. Enjoy the interview with Jonghee. 1. Tell us about when you first became interested in optics and photonics. When I was a high-school student, I had a great opportunity to attend a summer camp held in South Korea's Postech University. The camp program introduced various research areas, and provided lab tours to students. ⠀ One of laboratories I visited was doing biochemical research. The researchers showed me microscopic images of a chicken eggshell captured by scanning electron microscopy. At that time I had no idea about optics and microscopy, but I was hooked on the microscopic images. Since then I have become interested in microscopic imaging and op...
