The BYU Air Quality Research Lab studies the sources, effects, and mitigation strategies for a variety of air quality issues. We are particularly interested in the intersection of energy production and usage with environmental impacts. Recent research projects include designing and testing an advanced combustion system to reduce CO2 emissions, using ultra violet LEDs to inactivate pathogens in air, characterizing Utah dust events with changing climate conditions, and evaluating impacts of urban heating on climate and pollutant conditions.
