Office: ENG/2157


Dr. Stefan Preble received his B.S. degree from RIT in Electrical Engineering (2002), and Ph. D. in Electrical & Computer Engineering from Cornell University  (2007).  His research is focused on novel Silicon Photonic devices with the goal of realizing high performance computing, communication and sensing systems that leverage the high speed, bandwidth and sensitivity of light.  Professor Preble has received numerous awards recognizing his work, including a DARPA (Defense Advanced Research Projects Agency) Young Faculty Award and an AFOSR (Air Force Office of Scientific Research) Young Investigator Award. He also received a gold medal award in a Human Competitive Evolutionary Algorithms competition for his work on nature-inspired evolutionary photonics. He has numerous publications in high impact journals, such as, Nature Photonics, Optics Express, Applied Physics Letters and Physical Review Letters. He is a member of the Optical Society of America.
