Dr. Wierer is a Professor at North Carolina State University in the Department of Electrical and Computer Engineering. His research interests include semiconductor device physics and semiconductor materials science. Specifically, he is interested in researching electronic and optoelectronic devices with III-nitride semiconductors. Prior to joining NC State University, Dr. Wierer worked at Philips-Lumileds, Sandia National Labs, and Lehigh University. At Lumileds Advanced Laboratories his research focused on novel III-nitride light-emitting diodes (LEDs). This includes the development of the first high-power (1 Watt) flip-chip III-nitride LED, and seminal work on III-nitride photonic crystal LEDs. At Sandia National Laboratories his interests broadened into other III-nitride research areas including — solar cells, intersubband devices, layer intermixing, power electronic devices, ultra-violet LEDs, and nanowire LEDs. Most notable is his ground-breaking work on proposing laser diodes as an ultra-efficient light source for solid-state lighting. Dr. Wierer has authored or co-authored over 180 journal publications and conference presentations, and holds 42 patents, predominantly related to III-nitride devices. He is an associate editor for the IEEE Photonics Technology Letters journal. He is a senior member of the Institute of Electrical and Electronics Engineers and the Optical Society of America, and a member of the Illumination Engineering Society and the International Society for Optics and Photonics.
