As a researcher, I have made significant contributions to the development of biotechnologies for sustainable agriculture, directly addressing food security and sovereignty in Venezuela and with potential applications globally. My work focuses on the utilization of plant growth-promoting rhizobacteria (PGPR) native to the Andean region, offering solutions for soil bioremediation, biostimulation of horticultural crops, and biocontrol of phytopathogens, while demonstrably reducing the reliance on industrial fertilizers and agrochemicals that negatively impact the environment.

My recent doctoral research demonstrated that the application of PGPR in onion cultivation resulted in a 50% reduction in the use of inorganic NPK fertilizer, alongside improvements in photosynthetic activity and nitrogen assimilation, leading to enhanced yields. Furthermore, the research showed a significant improvement in soil microbiological and enzymatic properties under water deficit conditions, indicating enhanced soil quality, health, and overall agroecosystem resilience. This highlights the potential of PGPR as key agents in soil restoration and sustainable agricultural practices.

Notably, for the onion hybrid studied, we reported its tolerance to water stress, achieving consistent yields with a 35% reduction in irrigation water requirements. The study also documented the accumulated temperature and radiation needed for the complete productive cycle of this onion variety. These findings offer valuable insights for optimizing resource use and enhancing crop resilience in the face of environmental challenges, contributing to more sustainable and secure food systems worldwide. Furthermore, I have actively contributed to the scientific community as a co-author in review articles focused on bioinoculants, collaborating with international colleagues and demonstrating my commitment to advancing knowledge in this critical area.
