Key aspects of activity
- Root trait tradeoffs and synergies for nutrient acquisition and water uptake in tropical moist forests
- Tree root responses to global changes (e.g. drought, hurricane, increase of CO2)
- Fine-scale ecological interactions between plant roots and mycorrhizal fungi
- Root ecology and modelling integration
- Plant physiology
- I am an ecosystem ecologist. My main interest is understanding the effects of climate change on forest functioning. Specifically, how climatic disturbances (warming, elevated CO2, drought) may affect the rhizosphere (soil-roots-microbes interaction). Most of my experience is based on tropical forests; thus, a great part of my current research and future interest is on tropical ecosystems which are underrepresented in global databases and global ecosystem models.

Key aspects of activity
- I am an agronomist and ecosystem ecologist. My research mainly focuses on plants functional responses (mainly the belowground) to environmental gradients using trait-based ecology approach and relate them to ecosystem services, mostly in temperate ecosystems (agroforest, forest and crop systems); Developing methods of image acquisition and phenotyping.Iam also image analysis software enthusiast.
- Current research project: I am supporting the Earth Commission’s Working Group on Biosphere Interactions (“biosphere defenders”) which aims to specify the extent and integrity of biomes and ecosystems to stay within a “safe and just corridor” for people and the planet.
