Research Focus

Understanding how grapevines adapt to abiotic stresses and how these responses influence grape development, secondary metabolism, and ultimately wine composition and quality. Integrating viticulture, plant physiology, winemaking, analytical chemistry, and chemometrics, her work investigates how environmental factors affect berry chemical composition and key secondary metabolites such as phenolics, carotenoids, and aroma compounds. Using chemometric approaches to interpret complex grape and wine chemical datasets, this research links vineyard conditions and grapevine stress-adaptation mechanisms to measurable changes in grape and wine quality.
