Agricultural fertilizers help increase food production but also release nitrous oxide, a greenhouse gas nearly 300 times more potent than carbon dioxide. This research investigates conservation agriculture practices that support beneficial soil microbes capable of reducing these emissions, enabling sustainable food production while limiting agriculture’s contribution to climate change.

This research develops synthetic communities of beneficial xylem-inhabiting bacteria to control olive vascular diseases caused by Verticillium dahliae and Xylella fastidiosa. Over 300 bacterial strains were screened for biocontrol traits, and compatible candidates were combined into effective communities. Preliminary plant trials show promising results for sustainable, microbiome-based disease management.

This research examines whether long-term organic soil management improves climate resilience. Using a 27-year field experiment, the study shows that compost and manure significantly improve soil structure, reduce compaction, and increase water retention. Results demonstrate that sustained organic practices can transform fragile soils into resilient systems for future food security.

This research examines how climate change affects Phytophthora infestans, the pathogen responsible for potato late blight. By studying pathogen growth, reproduction, and molecular changes under future temperature and CO₂ conditions, the project aims to inform climate-resilient disease management strategies and strengthen global food security.

Varroa mites—long assumed to feed on bee blood—actually consume the honeybee’s fat body, a vital organ responsible for immunity, detoxification, and metabolism. Using fluorescent staining and artificial “decoy bees,” the study shows Varroa require fat body to survive and reproduce. Targeting this tissue could revolutionize strategies to protect collapsing honeybee populations.
