CCR IAM Staff: Leiwen Jiang
My research portfolio involves methodological work on improving demographic components of integrated climate assessment models and exploring the broader environmental implications of demographic dynamics. This effort consists of two parts. First, I explore the influence of demographic and other socioeconomic variables on various aspects of environmental issue, at a range of levels from the regional to the global. Second, my research aims to advance demographic modeling, particularly multistate population and dynamic household projections, in order to improve integrated assessment models. In particular, I am developing the demographic module of the iPETS integrated assessment model used in the IAM group at NCAR.
As extensions of the research on integrated climate assessment modeling, I explore the socio-demographic determinants of the energy transition in the developing world; investigate the effects of urbanization in various forms and phases and its effect on energy consumption, land use, and greenhouse gas emissions; model the interacting patterns of demographic dynamics (particularly migration), institutional arrangements, and the use of land/water resources; and study behavioral changes in housing, diet, transportation, etc. and their relationships with environmental and climate change.
Before joining NCAR, I was Assistant Professor (research) at Brown University, Associate Professor at Peking University, Guest Research at International Institute for Applied Systems Analysis (IIASA), and Senior Demography at Population Action International. I am currently serving as Lead Author in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report in Working Group III, and Panel Member of International Union for Scientific Studies of Population (IUSSP) Scientific Panel on Climate Change.
