About
I lead the Climate Dynamics Group at Chalmers University of Technology in Sweden. I’m an atmospheric and climate scientist studying climate variability and change, atmospheric dynamics, the Arctic climate system, terrestrial carbon cycle dynamics, and greenhouse gas emissions. In my research, I combine observations, theory, and numerical modeling to advance our understanding of the Earth system.
My current research focuses on developing methods to estimate CO2 emissions and uptake using primarily satellite observations. Specifically, I use data assimilation and inverse modeling techniques to infer regional-scale CO2 emissions and uptake from both natural and anthropogenic sources and sinks. Such methods are useful to study the natural carbon cycle and independently estimate anthropogenic fossil fuel emissions.
I’m also interested in various aspects of climate change, with a focus on the Arctic climate system and its connections to mid-latitude weather and climate variability and extremes. You can read more about the research topics that I and my group are working on under Research.
In my free time, I like to play basketball, listen to and play music, bike, and contribute to free and open-source software.
