Winston V. Schoenfeld is currently Director of the Solar Technologies Research Division (STRD) at The Florida Solar Energy Center (FSEC) and Professor of Optics at CREOL, The College of Optics & Photonics at the University of Central Florida. He received his Ph.D. degree in materials science from the University of California, Santa Barbara (UCSB) in 2000, and holds an MS and BS in Materials Science and Engineering from the University of Florida. Prior to joining CREOL, Dr. Schoenfeld served as Device Manager at Uniroyal Optoelectronics, working in the area of high brightness light emitting diodes (LEDs), and later in 2003 founded Medical Lighting Solutions, Inc., a supplier of specialty LED lighting solutions for the medical and biomedical industries. He has authored/co-authored more than 120 refereed journal publications in the areas of photovoltaics, the epitaxial growth and properties of oxide semiconductors, oxide and nitride-semiconductor light emitting diodes, self-assembled quantum dots, e-beam nano-lithography, quantum information/networks, comprehensive modeling of nanowire devices, and solid-state nuclear material detection. Dr. Schoenfeld is a Fellow of SPIE and currently serves as a Principal Editor for the Journal of Materials Research.
