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 Lehigh University, Dr. Wierer worked at Philips-Lumileds and Sandia National Labs. 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 pioneering 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 150 journal publications and conference presentations and holds 38 patents, predominately related to solid-state lighting. 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.
