I am BSc in Biology by the Universidad de Valencia (Spain, 2004) and PhD in Biotechnology by the Universidad Politécnica de Valencia (Spain, 2011). During my PhD, in the lab of Dr. José León (IBMCP, Spain), I studied the connections between nitric oxide (NO) and the phytohormones abscisic acid (ABA) and gibberelllins (GAs) and their involvement in plant development and stress tolerance. After my PhD, I joined the lab of Prof. Sean Cutler (University of California, Riverside, US), to gain experience in chemical genetics and ABA signaling. During my postdoc I became interested in the regulation of ABA receptors in crop plant species (maize, soybean, setaria and switchgrass) and I developed high-throughput chemical screening assays to identify novel ABA-receptor agonists in economically relevant plant species. Additionally, I set up genome editing protocols to generate mutants in dicots and monocots. Since I returned to Spain, to the lab of Prof. Pedro L. Rodíguez (IBMCP, Spain), in 2016 I have obtained funding to support my independent research line. First, with a Juan de la Cierva Incorporación (2016) and next with a Marie Curie Re-Integration grant (2017-2019). My goal is to generate biochemical, genetic and structural data on crop ABA receptors and exploit it to identify synthetic ligands able to activate drought resistance in the field. We have discovered some promising molecules able to activate ABA signaling in crops. I am collaborating with organic chemists and structural biologists to improve the potency of these compounds using structure-guided drug design. Alternatively we are also exploring the chemical space through a chemoinformatic approach using in silico pharmacophore screening and docking refinement to identify novel chemical scaffolds to control ABA signaling on demand.
