Carlos Sierra
I am a guest professor at the Department of Ecology. During my visit at SLU, I will work towards a better understanding of the effects of management on soil carbon sequestration and related climate feedbacks.

Presentation

My main research interest lies in the intersection between the global carbon cycle, theoretical ecology, and mathematics. I have a 50% appointment at the Department of Ecology in SLU, and a 50% appoitment at the Max Planck Institute for Biogeochemistry in Germany.

Research

Some of my main research questions include:

- For how long does carbon stay in terrestrial ecosystems and the entire terrestrial biosphere?

- How long would it take to remove carbon of fossil-fuel origen from the atmosphere-biosphere-surface ocean system?

- Can we adaptively manage terrestrial ecosystems to increase the time carbon remains stored before returning to the atmosphere?
