Research Interests
My research focuses on the effects of anthropogenic emissions of greenhouse gases and aerosols on climate on multi-centennial timescales. The goal is to better understand the response of the climate system to forcing and the interactions between climate system components (the atmosphere, ocean, land surface, biosphere and cryosphere) in order to improve predictions for the future. To achieve this objective, I use climate models of different complexity, from simple conceptual models to complex Earth System models.

Research Project
Land and ocean carbon sinks play a major role in regulating atmospheric CO2 concentration and climate. However, their future efficiency depends on carbon cycle feedbacks in response to changes in atmospheric CO2 concentration and climate. Through my research, I hope to gain insight into the approach best suited to quantify carbon cycle feedbacks under negative CO2 emissions, and into the role of these feedbacks in determining the effectiveness of negative emissions technologies in reducing CO2 levels.

Research Project
Afforestation/reforestation carried out on a globally significant scale can increase or decrease streamflow, soil moisture, water table level, evapotranspiration, and water recycling depending on the season and location. This carbon dioxide removal method also increases the quantity of secondary organic aerosols released to the atmosphere compared to grasslands of equal extent. Furthermore, some of these aerosols play a major role in cloud droplet formation, with consequences for cloud formation and albedo. My research aims to quantify the impact of afforestation/reforestation on the water cycle and planetary albedo to the end of the 21st century for high carbon dioxide emissions scenarios.

Research Project
Anthropogenic climate change is driven by greenhouse gas emissions in the atmosphere. We see consistent increases in atmospheric CO2 concentrations and global temperatures. However, the northern latitudes are disproportionately affected by climate change extremes. As temperatures reach unprecedented highs, we risk crossing thresholds in the earth system. In my research, I aim to explore the effects of passing these thresholds such as permafrost melt or ice sheet disintegration.
