I have 14 years of experience in tropical ecology. My main interests have been nutrient cycling in tropical forests, plant response to climate change and most recently, the belowground rhizosphere in the tropics.

Amazon, Bolivia

I worked in the Bolivian Amazon measuring plant productivity. One major goal is to extend measurements in this country, especially belowground productivity and root traits.

I am part of the Tropical Response to Altered Climate Experiment project in El Yunque Puerto Rico. This is the first warming experiment of the Neotropics! My job as a PhD. student there was to measure root response to temperature increase, and to Hurricane disturbance

NGEE Tropics

As a PhD. student, I was part of the NGEE Tropics project. My job here was to study fine root traits in some of the most common plant species of the Puerto Rican wet forest in Luquillo, and correlate them with soil phosphorus (P)  available in order to infer different plant strategies used for P acquisition. The main goal was to be able to generalize the correlations in different wet tropical ecosystems

Tropical Root traits- TropiRoots

TropiRoots is initiative of root ecologists from tropical regions where we aim to organize, synthesize, and publish as much data on tropical root traits.

The illustration shows fine-root diversity of morphological traits in a forest site of Puerto Rico. Some of the traits that we are interested in are root morphology, dynamics, chemistry, physiology, and microbial associations

My ambitions

Enthusiastic and dedicated, I’m seeking to collaborate with projects willing to include the root component in their NPP calculations, or any biogeochemical processes. With relevant experience in tropical ecosystems, proficient at 3 different languages and the statistical language R, I believe I can be efficient in the filed work, communicating the science with local communities, and analyzing the data.

I am a tropical ecologist working as a postdoctoral researcher at the University of Hamburg. 

My main interests are:

  • 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
