She began her teaching and research career in 1985 in the Department of Analytical Chemistry of the Faculty of Chemical Sciences of the UCM. In 1989 she presented her doctoral thesis on automatic methods of analysis. She undertook a postdoctoral stay at the University of Hull with Professor Alan Townsend to develop procedures for enzyme immobilization and coupling of enzyme detection systems in liquid chromatography. Upon her return to the Department of Analytical Chemistry, her research focused on methodological developments in chromatography for the analysis of compounds of interest in food and the environment. Currently, her lines of research are focused on the analysis of polyphenols using capillary LC in foods and the extraction of high-value compounds from waste products of the food industry. She has been a Professor since 2018 and has participated in management tasks at the University as Secretary or Vice-Dean of Studies of the Faculty of Chemical Sciences, as coordinator of the Master's Degree in Chemical Science and Technology, and as a Member of the Advisory Commission for Bachelor's and Master's Degrees at the UCM.
