In the master’s thesis work, he did research on the partitioning of Evapotranspiration (transpiration and evaporation) using stable water isotope techniques for the whole of Costa Rica (the manuscript is currently under review). In 2020, ‘Albi’ joined Isodrones as a Ph.D. student. In his doctoral thesis, he will conduct research on isotope labeling techniques combined with in situ soil and plant water isotope measurements for estimating groundwater recharge in the dry parts of Honduras and Costa Rica.
