Welcome to the Aerosol and Air Quality Research Laboratory

The Aerosol and Air Quality Research Laboratory (AAQRL) is housed in the Department of Energy, Environmental and Chemical Engineering​ at Washington University in St. Louis. Our focus is on research and education related to particulates in gaseous suspension, known as aerosols. AAQRL’s contributions to this field span the full process of technology development, from synthesis and characterization to eventual application. Through this research, we aim to mitigate the negative impacts of aerosols on the environment and leverage their potential for positive contributions to society.

Applications of aerosol science and technology include nanoparticle synthesis, advanced material synthesis, pharmaceuticals, medicine, biological systems, electronics, air pollution control, atmospheric issues, global climate change, and energy.​

We invite you to take a virtual tour and learn more about us, and the exciting field of Aerosol Science and Engineering.​
