Brett C. Singer is a Staff Scientist and Principal Investigator (PI) in the Energy Technologies Area of Lawrence Berkeley National Laboratory. Dr. Singer is the Leader of the Indoor Environment Group and co-leader of Indoor Air Quality research in the Residential Building Systems Group. 

Dr. Singer has conceived, conducted and led research projects related to air pollutant emissions, physical-chemical processes, and pollutant exposures in both outdoor and indoor environments. His research aims to understand the real world processes and systems that affect air pollutant exposures. His guiding professional motivation is to provide the scientific basis to inform energy and environmental policy.

Dr. Singer leads the Indoor Environmental Quality project within the US-China Clean Energy Research Center Building Energy Efficiency Program.

A major focus of Dr. Singer’s work over the past decade has been the study of environmental quality and risk reduction in high performance homes. The goal of this research is to accelerate the adoption of IAQ, comfort, durability and sustainability measures into new homes and retrofits of existing homes. This is achieved through the mechanisms of buildings codes and standards; training of builders and contractors; public education; and technology development – all supported by robust research. The IE and RBS research groups conduct in-home studies, controlled laboratory experiments, simulation-based studies and data analysis to identify the most effective and energy efficient air quality control strategies.

Dr. Singer’s early career research examined on-road motor vehicle emissions and the effectiveness of California’s Smog Check program. His first project at LBNL examined the sorption of secondhand smoke compounds, an effect that contaminates materials and leads to extended odors and pollutant exposures. This work helped launch interest in the study of “thirdhand” smoke. 

Dr. Singer has authored or co-authored over 50 papers in archival, peer-reviewed journals and dozens of technical reports and peer-reviewed conference papers.

Education and Honors:

2016: Named to the Academy of Fellows of the International Society of Indoor Air Quality and Climate.

1998: Ph.D. in Civil & Environmental Engineering from the University of California, Berkeley. 

1991: B.S. in Mechanical Engineering from Temple University (Summa cum Laude).
