For years, Penélope García-Angulo's research interest has been focused on plant cell wall polymers such as cellulose, hemicelluloses, pectins, and lignin, and their plasticity under stress situations, as some of the cell wall modifications that take place during stress could have important biotechnological applications. As part of this research, she has worked with in vitro cultures of different species (bean, maize, poplar, grape, hops…). She currently works at the Faculty of Biological and Environmental Sciences, University of León. Penélope researches in Plant Physiology, development, and Biotechnology.
