Ziying (Nancy) Lei, Ph.D
Assistant Professor,
Department of Chemistry
Nancy's research is centered on the detailed physicochemical characterization of atmospheric aerosol particles and their ice nucleation ability, employing cutting-edge microscopic and spectroscopic methods. Currently, she serves as a Co-Principal Investigator on a Department of Energy-funded project. Her goal is to understand the physical properties and chemical composition erosol particles collected during the TRACER (Tracking Aerosol Convection Interactions Experimental) Field Campaign
