Allison C. Aiken is a senior scientist with a PhD in analytical chemistry from CU Boulder who has been at LANL since 2010. Her expertise is in developing new measurement techniques and analytical methods for particles sampled in and collected from complex environments like the atmosphere as well as conducting controlled laboratory and field experiments for model validation. She is the co-founder and co-Director of the Center for Aerosol and Trace Gas Forensics (CAFE) at LANL and is the point of contact for U.S. DOE Atmospheric Systems Research (ASR) at LANL.
Her research focuses on the dynamic nature of aerosols to understand changes in chemistry, optical properties, water uptake, and the physical properties that drive particulate transport, growth, cloud processing, and atmospheric lifetimes. She is experienced in leading bulk and single-particle aerosol analysis of wildfire events, wildfire urban interface (WUI) controlled experiments, and detonations.
Aiken has two LANL Large Team Distinguished Performance Awards, >16,000 peer-reviewed citations, and has served on numerous advisory boards, including as Chair of the U.S. DOE Atmospheric Radiation Measurement User Executive Committee.
