Co-Principal Investigator in the FCT project GrapeMicrobiota (PTDC/BAA-AGR/2691/2020): «Metabolome-microbiota interactions in 3 grapevine cultivars of DOC Douro region - exploitation of the microterroir to enhance the typicity of wine», inserted in the goals of ADVID-CoLAB Vines&Wines. Physiological, biochemical, and high-throughput analytical assays to understand core mechanisms regulating calcium distribution and partitioning in the grape berry (Vitis vinifera L.), the effects in hormonal balance and the implications in grape and wine quality.
