Aerosol Research Laboratories

Scientists in Aerosol Research Laboratories conduct a wide range of aerosol research funded by federal agencies using advanced instrumentations. The comprehensive array of measurement tools acquired commercially and developed in house have been employed to investigate transport and transformation of airborne particles in the atmosphere, real-time detection of toxic airborne particles in industrial workplaces, control of engineered nanoparticles, laser ablation for surface decontamination, and lately the impacts of nanoparticles on biological tissues. Supporting infrastructure to the laboratories includes methodologies for high precision particle generation and delivery developed for instrument calibration and aerosol metrology for biological research.
