People of EMDL
Director: Dr. Steven Ringel
Professor Ringel leads an internationally recognized research program that strives to advance the basic science and engineering of
electronic materials, nanostructures and devices that will impact alternative energy, electronics, photonics and sensing technologies.
As the Neal A. Smith Endowed Chair in Electrical Engineering, Professor Ringel is particularly focused on issues related to renewable,
clean and sustainable energy sources and efficient utilization of electric power, and how introduction of functional materials and
nanostructures can advance technologies and systems used in these arenas.
