Finlayson-Pitts is Canadian-American atmospheric chemist.
She is a professor in the chemistry department at the University of California, Irvine and is the Director of AirUCI Institute.
Finlayson-Pitts and James N.
Pitts, Jr.
are the authors of Chemistry of the Upper and Lower Atmosphere: Theory, Experiments, and Applications (1999).
She has been a member of the National Academy of Sciences since 2006 and is the laureate for the 2017 Garvan–Olin Medal.
In 2016 she co-chaired the National Academy of Science report "The Future of Atmospheric Chemistry Research" Finlayson-Pitts investigates the chemistry of the upper and lower atmosphere and ways in which chemical reactions in the atmosphere are involved in air pollution and climate change.
She and her team work to develop a molecular-level understanding of gaseous reactions of particles in different layers of the atmosphere, and at the interfaces between layers.
They also study the interface between air and water.
She emphasizes the "urgency for addressing climate change at all levels of government in the U.S.
