Professor Kyung-Hoon Shin's research lab specializes in atmospheric chemistry and environmental science, focusing on the role of biogenic emissions—particularly marine-derived dimethyl sulfide (DMS)—in aerosol formation and their impacts on Arctic air quality and climate. The lab investigates the complex interactions between marine ecosystems, atmospheric chemistry, and aerosol microphysics, especially during seasonal transitions such as phytoplankton blooms. Using long-term, concurrent measurements of atmospheric gases, aerosol size distributions, and chemical composition, the lab aims to quantify the contribution of biogenic sulfur to secondary aerosol formation in polar regions. Their work contributes to improving climate models by better understanding the feedback mechanisms between oceanic biological activity and atmospheric particle formation in the Arctic.

Abstract. The connection between marine biogenic dimethyl sulfide (DMS) and the formation of aerosol particles in the Arctic atmosphere was evaluated by analyzing atmospheric DMS mixing ratio, aerosol particle size distribution and aerosol chemical composition data that were concurrently collected at Ny-Ålesund, Svalbard (78.5° N, 11.8° E), during April and May 2015. Measurements of aerosol sulfur (S) compounds showed distinct patterns during periods of Arctic haze (April) and phytoplankton bloo
