Stead's research explores gene expression and proteomic changes during floral senescence in species like Alstroemeria, Arabidopsis, and daylilies. His group investigates how dehydration, storage conditions, and preservatives alter molecular pathways, aiming to develop diagnostic tools for flower quality assessment.

Recent publications emphasize postharvest challenges in ornamental and agricultural crops, including metabolic dynamics in lilies, mycorrhizal interactions in rosemary, and cold tolerance in basil. His team employs transcriptome analysis, microarray technology, and hyperspectral imaging.

• Key projects: Methane removal methodologies (2017-2019), Dahlia flower quality improvement (2014-2018), mycorrhizal manipulation for vegetable crops (2009-2013)
• Techniques: GeneSpring software, 2D gel electrophoresis, cDNA libraries

The research has practical applications in floral preservative formulation, breeding programs, and quality assurance for the UK cut flower industry.
