As part of the Center for Aerosol Impacts on Climate and the Environment (CAICE), our group is involved in a variety of projects centered on understanding the production and climate impacts of sea spray aerosols. With the invention of the Marine Aerosol Reference Tank (MART), focused lab studies on the chemistry of nascent sea spray aerosols are now possible and currently being pursued. Examples of lab experiments in our lab as part of CAICE:

Instrument development is also an important element of our laboratory-based work. We design novel instrumentation to investigate a wide range of systems, both atmospheric and non-atmospheric. Examples of past and current instrument development:
Field Study-inspired Experiments
Part of our goal in the Prather lab is to better understand ambient reaction processes. Thus, results from field studies are used to inform and design specific lab studies that can address field observations. Examples include:
Applications of Single Particle Mass Spec to Non-atmospheric Systems
The ATOFMS instruments provide a unique ability to perfform on-line laser desorption mass spectrometry with much higher throughput than standard off-line MALDI methods. Taking advantage of these capabilities, our group also performs non-atmospheric measurements of pharmaceutical aerosols (inhalers), petroleum-based particles (various oil and fuel formulations), cigarette smoke, meat cooking, welding fumes, metallic nanoparticles (iron, gold and silver), copy machine emissions, MOFs, and single cancer cells.
