Susanne V. Hering Award
Recognizes outstanding contributions to aerosol science with a special emphasis on work that has had a significant impact on public health, the built environment, or the global ecosystem.
Linsey Marr
Charles P. Lunsford Professor of Civil and Environmental Engineering at Virginia Tech
Prior to the Covid-19 pandemic, Marr was one of only a few scientists in the world who studied viruses in the air. She has worked to update conventional wisdom about virus transmission and to recommend guidelines for protecting public health. She has been interviewed hundreds of times, contributed op-eds to the New York Times and the Washington Post, and provided scientific input for numerous videos and visualizations aimed at the general public. Her efforts contributed to the recognition of airborne transmission of Covid-19 by the World Health Organization and Centers for Disease Control.
She has also served AAAR as Treasurer and member of several committees. She is on the editorial advisory board of Aerosol Science & Technology, AAAR’s Journal.
Sheldon K. Friedlander Award

Apoorva Pandey
Ph.D. from Washington University in St. Louis, 2019 (adviser: Rajan Chakrabarty)
Pandey’s winning dissertation findings are influencing measurements in national particulate monitoring programs and encompassed three main research parts, each of which could have stood by itself as a dissertation. They are:
- Single parameter representation of scattering directionality for soot aggregates in algorithms and models.
- Characteristics and emission factors of light-absorbing organic aerosol from field experiments in South Asia.
- Estimating aerosol-phase light absorption from filter-based optics.
Pandey has also published ten peer-reviewed publications, six of which she authored.
Benjamin Y.H. Liu Award

Yongle Pan, Ph.D
Senior Research Physicist & ARL Fellow, CCDC -US Army Research Laboratory (2009-present)
Primary research achievements:
- Pioneer in developing real-time, in-situ point-detection systems for biological and chemical aerosol threats.
- Laser spectroscopic diagnostics for biological, chemical, & atmospheric aerosol particles.
- Optical-trapping and property study of single airborne aerosol particles.
- Expert in the research field for aerosol detection and characterization.
Yongle Pan has published approximately 150 peer-reviewed journal articles, three book chapters, has received nine US patents awards, and has over 3,700 citations.
Thomas T. Mercer Award
Recognizes excellence in the areas of pharmaceutical aerosols and inhalable materials.
Robert F. Phalen, Ph.D
David Sinclair Award
Recognizes sustained excellence in aerosol research and technology by an established scientist still active in their career. The individual’s research must have a lasting impact in aerosol science.
Peter Buseck
Kenneth T. Whitby Award

Dr. Jason Surratt
Professor, University of North Carolina-Chapel Hill in the Department of Environmental Sciences and Engineering located within the Gillings School of Global Public Health, as well as in the Department of Chemistry located within the College of Arts and Sciences
His current research combines advanced mass spectrometry techniques with synthetic organic chemistry during laboratory and field studies in order to understand as deeply as possible the atmospheric chemistry that occurs in both the gas and condensed phases, with special focus on the chemistry leading to the formation of secondary organic aerosol (SOA). His research has helped to derive model parameterizations that more explicitly predict atmospheric levels of isoprene-derived SOA, and has helped to reveal the importance of acid-catalyzed multiphase chemistry in SOA formation. More recently, he has served as the Director of the NC Per- and Polyfluoroalkyl Substances (PFAS) Testing Network, which has helped to uncover the types of PFAS present in atmospheric fine aerosols collected from NC air.
He is the recipient of the 2012 Health Effects Institute Walter A. Rosenblith New Investigator Award, the 2013 American Association for Aerosol Research Sheldon K. Friedlander Award, and the 2016 James J. Morgan Environmental Science & Technology Early Career Award Lectureship.
Dr. Surratt has also authored and co-authored more than 150 peer-reviewed articles in aerosol science, atmospheric chemistry, and air pollution journals.
Aerosol Science & Technology Outstanding Publication Award
This award is bestowed annually to one article published in AS&T without regard to publication date. The award recognizes articles that have had a significant impact on the field.
M. E. Birch & R. A. Cary
“Elemental Carbon-Based Method for Monitoring Occupational Exposures to Particulate Diesel Exhaust”
Aerosol Science and Technology 25:3, 221-241 (1996)
This paper introduces a thermal-optical instrument for the determination of elemental carbon and organic carbon content of carbonaceous aerosol collected on filter. The publication established operational definition of elemental carbon as used today and it described a thermal-optical method to quantify elemental and organic carbon content, which was later adopted in a commercially available EC-OC analyzer instrument from Sunset Laboratories Inc and the NIOSH method 5040, both of which are widely used today. The publication, with over 1300 citations, has made irreplaceable contributions to our ability to characterize carbonaceous aerosols and their impact on human health and the climate.
