Demetris L. Geddis is the Assistant Dean of the School of Engineering, Architecture, and Aviation and Professor of Electrical and Computer Engineering at Hampton University. Dr. Geddis earned his Bachelor of Science in Electrical Engineering from Hampton University (’98) and Master of Science and Ph.D. in Electrical and Computer Engineering from the Georgia Institute of Technology. He has extensive research experience in the areas of integrated optoelectronics, photonic integrated circuits, micro and nanofabrication, and semiconductor materials. Dr. Geddis has worked as a Research and Design Engineer at Motorola and Bell Laboratories. He has also worked at the NASA Langley Research Center as a NASA Faculty Fellow for the Nondestructive Evaluation Sciences Branch where he performed research in the area of optical fiber sensing for real time health monitoring of aerospace vehicles. Currently, Dr. Geddis serves as the Principal Investigator of the Hampton-Brandeis Partnership for Research and Education in Materials (PREM), which is a six-year NSF-funded program that brings together faculty and students from engineering, physics, and chemistry to forge new knowledge in the area of integrated photonic materials.
