He finished his PhD in (Biological) Science in 2004 at the University of the Balearic Islands (UIB). His research career has always been linked to various aspects of plant biology, focusing on the response of plants to water deficit and its production capacity under Mediterranean conditions. At the beginning of his career, Dr. GulÝas participated in studies on plant response to water deficit in species of agronomic interest in Mediterranean areas, mainly forage species and grapevine. Subsequently, he completed his PhD in Comparative ecophysiology of Mediterranean shrub species, in which he addressed studies on the effect of water stress on photosynthesis and the regeneration of populations in Mediterranean environments. After the defense of the doctoral thesis, he continued his studies in species of agronomic interest, expanding the productive approach to other areas such as the usefulness of indigenous species and varieties of the Balearic Islands in revegetation and gardening in Mediterranean climate areas.
Moreover, his teaching activity has been developed in the Degree on Agricultural Engineering (recently transformed into degree in Agricultural Engineering and Rural Environments) since 2003 as an Associate Professor in the Plant Production section of the Department of Biology at UIB, focusing their teaching in gardening and plant nurseries. He also is co-director of the Master in Applied Biotechnology and coordinator of mobility of the degree in Agricultural Engineering and Rural Environments On the other hand, he has lead several cooperation projects focused on the selection of plant species economically interesting in sustainable development of different areas in Bolivia.
