Biography

Michael joined PNNL as a Lighting Engineer in 2011 and works in PNNL's Portland office. Working for the Department of Energy's Solid-State Lighting program, he focuses on technology development issues, helping to improve product performance through research, testing, standards development, and engagement with various elements of the lighting industry. Michael is a principal investigator for the CALiPER program, and manages the Metrics and Standards program. He has also developed a human factors research agenda that is currently focusing on color rendition.

Michael is a member of the Illuminating Engineering Society's (IES) Color Committee, and was the chair of the IES Color Metrics Task Group, which developed TM-30-15. He is also a member of the IES Technical Procedures Committee (TPC), and has served as a guest editor for LEUKOS' special edition on color rendition. Prior to joining PNNL, Michael earned a Ph.D. in Architectural Engineering from Penn State University, receiving the 2013 Taylor Technical Talent Award from the IES for his published work. Michael was named a future leader of lighting by LD+A Magazine in 2010, and has authored over 50 journal articles and government reports.
