Biography

Dr. John Shilling is an early-career atmospheric chemist at PNNL with expertise in measuring aerosol gas- and particle-phase chemical composition and gas/particle interactions. He came to PNNL in 2008 as a staff scientist and led a project to design and build an aerosol measurement laboratory and environmental chamber in PNNL's Atmospheric Measurement Laboratory (AML). Dr. Shilling is an expert in aerosol gas and particle measurements and in applying mass spectrometry to problems in atmospheric chemistry. Currenly, he is conducting laboratory experiments investigating the lifecycle of organic aerosol particles and their climate-relevant properties. Dr. Shilling has also applied his mass spectrometry expertise to field studies. He served as the principal investigator for both gas- and particle-phase mass spectrometers deployed onboard the G-1 research aircraft during several field campaigns including CARES, TCAP, BBOP and GoAmazon (upcoming).
