I am interested in understanding how carbon cycling, ocean acidification, and hypoxia/anoxia respond to climate change and finding solutions to mitigate the negative effects. My research efforts have focused on (1) carbon cycling dynamics and air-water CO2 flux in diverse marine ecosystems, (2) climate change effects on biogeochemical processes (particularly carbon cycling, ocean acidification, and deoxygenation) and interactions of leading environmental multiple stressors, and (3) exploring innovative methods (e.g., carbon dioxide removal, ecosystem recovery) to mitigate global warming and ocean acidification.
Carbon cycling is key to understanding global warming as well as the services the ecosystem provided. We are interested in understanding the carbon cycling dynamics in wetlands, estuaries, coastal oceans, and the Arctic Ocean, particularly focusing on how carbon cycling is modulated by climate change and human activities. We primarily investigate inorganic CO2 system in these systems to address their heterogeneity and controlling mechanisms and past-current-future trends using carbonate parameters (dissolved inorganic carbon, total alkalinity, pH, partial pressure of CO2) and carbon isotopes and many other approaches (sea-going field monitoring, field and lab experiments, CO2 sensors in mooring and autonomous instruments).
Climate change is exacerbating carbon cycling tightly coupled leading environmental stressors (e.g., Ocean acidification, hypoxia/anoxia) which impact ecosystems, fisheries, and coastal communities. We are interested in understanding how climate changes affect these environmental stressors and how their interactions affect carbon cycling additively and synergistically or counteract each other. We put much of our efforts investigating two of the most sensitive hotspots globally (coastal ecosystems and the Arctic Ocean) where human activities and sea-ice melt significantly affect the decadal changes and marine ecosystems, separately. We further strive to explore innovative approaches to mitigate the negative effects of ocean acidification (production of calcium carbonate) and global warming (carbon dioxide removal).
