Real-time detection and characterization of biological and chemical aerosol particles at a trace level in atmosphere

Atmospheric aerosol particles play an important role in climate and health. Detection and characterization of aerosol particles, especially the particular particles such as these formed by biological and chemical agents, has become increasingly important for a wide variety of research communities and scientific questions in both outdoor and indoor environments. The presentation here will focus on the development of real-time, in-situ aerosol detection and characterization systems at CCDC-ARL, mainly based on single micron-sized particle fluorescence spectra, two-dimensional angular optical scattering patterns, and Raman spectroscopy, including the recent work on laser-trapping system for airborne aerosol particles, and the new results from time- and position-resolved Raman spectroscopy of single laser-trapped airborne particles.

 

Biography
Dr. Yong-Le Pan is a Research Physicist at Environmental Sensing Branch, CISD, CCDC-Army Research Laboratory since 2009. He was elected to be a Fellow of the US Army Research Laboratory in 2013. His PhD is in Laser Physics and Molecular Spectroscopy from East China Normal University in 1993. From 1993 to 1999 he was an Assistant Professor, then Associate Professor at Fudan University. From 1997 to 2008 he was a Visiting Professor, then Senior Research Scientist (Full Research Professor) at Yale University. He has been working on real-time, in-situ aerosol detection and characterization systems for years, mainly based on single particle fluorescence spectra, two-dimensional angular optical scattering patterns, and Raman spectroscopy. Some of the advancements have been transitioned to DARPA, DTRA, DHS, USAMIID, ARL, ITT, and SNL. He has over 130 refereed journal papers, 3 book chapters, and 11 patents, over 3000 citations. He has successfully completed more than 20 research projects supported by DARPA, DTRA, JBTDS, DHS, ARO, AFOSR, DOE as a principal investigator (PI) or Co-PI.
