Biography

Dr. Swarup China is a chemist with the Biogeochemical Transformations team in PNNL’s Environmental Molecular Sciences Division and the Environmental Molecular Sciences Laboratory (EMSL) user program. His significant research areas include the atmospheric aerosol properties and processes, atmospheric aerosol chemistry, heterogeneous ice nucleation, and aerosol-cloud interactions. He utilizes field studies, laboratory measurements, and off-line analysis with multi-modal analytical techniques, such as microscopy, spectroscopy, and high-resolution mass spectrometry to study atmospheric processes and interactions between ecosystems. China also studies the chemical aging of atmospheric particles through multi-phase atmospheric chemistry and investigates the effect of physicochemical properties of complex atmospheric particles on aerosol microphysical properties and cloud development. He aims to better understand the physical chemistry of atmospheric particles controlling aerosol-cloud interactions.
