The Aerosol Research Lab is located in the Science Research Building of the Faculty of Engineering and Architecture at AUB. It is home to an interdisciplinary research group with backgrounds in aerosol dynamics, chemistry, combustion, computational fluid dynamics, instrumentation, and controls. We study tobacco smoke, urban and indoor air pollution and its sources, and fundamental problems in aerosol transport phenomena. The Lab is equipped with a variety of particle sampling, sizing, and generation instruments, as well as a unique digitally-controlled tobacco smoking machine that can mimic real smoker behavior. The lab often operates in partnership with the Atmospheric Chemistry Group in the AUB Chemistry Department, and has access to HPLC-MS, GC-MS, and ICP-MS instruments at the Core Environment Lab and at the Central Science Research Lab at AUB. The lab also has open access to a modern, CNC-equipped machine shop located in the same building.
