BIOGRAPHY:

My research interests aim in understanding the role aerosols play in the Earth system, by studying the interactions and feedbacks between the atmosphere, the terrestrial biosphere, the ocean, and climate. I am currently working on a variety of topics related to aerosol research and their sources, sinks, and interactions with climate at various levels of complexity. My studies range from detailed aerosol processes such as the formation of secondary organic aerosols (SOA), to centennial time scale climate variability related to natural variability and external forcings. While my main expertise is organic aerosols, I am also experienced in working with all other aerosol types as well as tropospheric gas-phase and heterogeneous chemistry. I have extensively used both box models that I developed, and 3-dimensional global models: the TM3 chemistry/transport model, the IPSL general circulation model LMDz-INCA, and the GISS modelE Earth System Model (ESM), for which I had contributed to the IPCC AR5 model development. Currently I am working with the next generation of the NASA GISS ESM, the GISS ModelE2, which is part of CMIP5.
