I am interested in studying the potential effects of ecological stresses, specifically drought, disturbance, and salinity, in forest ecosystems at tree-level scale and how can this understanding informs a global perspective. Moreover, I want to determine how forests' ecosystems react to more frequent and severe ecological stress events due to climate change.

I use different measurements at tree-level and based on statistical analysis, remote sensing data, and numerical models scale to a larger level. I collect and process different types of data such as meteorological, bio-geochemistry, energy, and water fluxes to determine the potential sources causing stress in vegetation. I am addressing this question by combining high-frequency resolution data of evapotranspiration with self-made transpiration Granier-Style sensors deployed in the field, and other in situ measurements of stem water potential and water sources used by vegetation using d18O and d2H isotopes analysis.
