John has been covering the photonics industry at Laser Focus World for more than 12 years and, as Senior Editor, enjoys serving as the magazine's technical resource. John graduated from Rutgers University with a bachelor's degree in mechanical engineering and physics, and from the University of Rochester with a master's in optics. While at Rutgers, he helped construct an elementary-particle detector later installed at Cornell University, and carried out a research project on selective coatings for solar collectors.
Between degrees John worked at Exxon Research and Engineering, where he developed optical mounts used at Brookhaven National Laboratory's National Synchrotron Light Source. After college, he did R&D on multichannel optical-disk technology at Eastman Kodak, and subsequently spent 14 years developing optical systems in the photolithography industry.
