Professor Herman directs a large and collaborative research group that develops and applies laser technology and advanced beam delivery systems to control and harvest laser interactions in new frontiers of 3-D nanofabrication. Our mantra is: “We begin with light and we end with light devices.” To this end we are inventing new methods for processing internally inside optical materials that carve out highly compact and functional lightwave circuits, microfluidics, optofluidic systems, biophotonic sensors, and smart medical catheters. Our end goals are inventing new manufacturing processes and extending optical device and Lab-on-a-chip concepts towards more compact Lab-on-a-fiber and Lab-in-a-film microsystems.
