The Electronic Materials and Devices Laboratory (EMDL) is comprised of students and senior researchers with diverse backgrounds across the disciplines of Electrical Engineering, Physics, Materials Science, Chemistry, and Chemical Engineering. Such breadth allows vertical integration of research in electronic materials, nanostructures, optoelectronics, photovoltaics, electronics, device fabrication and integrated systems. The interdisciplinary philosophy of research within EMDL grants a unique perspective and results in extensive collaboration with other groups, at OSU and beyond.


The Electronic Materials and Devices Laboratory (EMDL) at Ohio State is located in the Department of Electrical Engineering and is directed by Professor Steven A. Ringel. For more information about activities and opportunities, please contact the EMDL Executive Assistant, Ms. Jennifer Donovan, at
