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?
