Research

My research interest lies in how climate is changing, what drives these changes over regional to global scale, and what are the associated dynamic mechanism. I am particularly interested in the impact of man-made climate forces (i.e., greenhouse gases and aerosols). Anthropogenic forcers have different radiative effects that some are absorbers (i.e., greenhouse gases, black carbon) that warm up the atmosphere while some are scatterers (i.e. sulfate) that cool down the atmosphere. In the real world, they are co-emitted and have strong spatial heterogeneity, and internal variations are important for regional climate, such as for the Pacific Coast of North America. This adds more complexity to disentangle the contribution of each forcer. 

In addition, anthropogenic aerosols cause severe air pollutions. Many countries are committed to reducing anthropogenic emissions for achieving sustainable development goals. This also attracts my attention in finding out the possible climate response to regional emission reductions. It could provide insights on adaptation and mitigation strategies.
