  • M.Sc., Physics, Free University Berlin, Berlin, Germany (1998)

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.

  • B.Sc., Geoecology, Technical University of Braunschweig, Braunschweig, Germany (2010)

Research Interests

My main research interests lie in climate change and ocean acidification as well as in the related changes in the biosphere. In particular, I am interested in the question how the Earth system responds to different future scenarios of anthropogenic greenhouse gas emissions that eventually reach the same cumulative emissions but differ in the emissions trajectories, including overshoot scenarios with negative carbon dioxide emissions.

  • B.A., English, St. Francis Xavier University, ON, Canada (2012)

Research Project

My research focuses on afforestation/reforestation as methods to mitigate climate change. The process is simple: by planting trees or allowing forests to regrow, carbon dioxide is removed from the atmosphere, which should help reduce global warming. This approach has impacts on the global carbon cycle, nitrogen cycle, forest ecosystems, land use allocation, & etc., that must all be accounted for to determine the effectiveness of afforestation/reforestation. During my Ph.D. I am investigating this effectiveness through climate model development and Earth system simulations.

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.

  • MFA, Creative Writing, University of British Columbia, BC, Canada (2010)
  • BFA, Creative Writing, University of British Columbia, BC, Canada (2008)

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.

  • B.Sc., Physical Geography (Honors), University of Victoria, BC, Canada (2018)

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.
