Research activity

I'm interested in the water and nutrient uptake dynamics of forests. This includes investigating root water- and nutrient uptake, transport, and incorporation into biomass. I work in mixed and pure species forests of the temperate and boreal region, and in ecosystems with different water and nitrogen availabilities. In the future I am interested to see if, and how this heterogeneity is translated into the soil, and how this influences soil water recharge and nutrient retention/leaching.


Currently, I work on the following questions in particular:

  • To what extend do roots reach for either water or nutrients horizontally and vertically?
  • How much is nitrogen uptake influenced by mass flow?
  • How do trees compete for nutrients with other players in the ecosystem and are mycorrhizal networks moving nutrients around to provide them to their tree hosts?
