Dr. Wierer’s 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 to encompass other III-nitride research areas including — solar cells, intersubband devices, layer intermixing, power diodes, ultra-violet LEDs, and nanowire LEDs. Most notable, is his ground-breaking work on laser diodes as an ultra-efficient light source for solid-state lighting.

Dr. Wierer has authored or co-authored over 100 journal publications and conference presentations, and holds 29 patents, predominately related to solid-state lighting and LEDs.

He is a senior member of the Institute of Electrical and Electronics Engineers, and member of Optical Society of America and Illumination Engineering Society.
