Prof. Penuelas is one of the most respected, cited and influential ecologists working today in the world; no one working in global ecology can afford not to engage with his work. Professor Josep Penuelas is internationally recognized for his innovative research on global change ecology, remote sensing and atmosphere-biosphere interactions which has had enormous impact. He is specially known for his pioneering work on the discovery of ecophysiological mechanisms linked to the use of carbon and oxygen use that helps to explain the diversity and distribution of aquatic and terrestrial plants; the development of increasingly used remote sensing techniques to assess plant and ecosystem functioning (e.g. he codeveloped the PRI, photochemical reflectance index, and t'he WBI, water band índex, that ser are becoming established tools in remote sensing of natural and agricultural ecosystems); the discovery of current evidences of global change, climate change, and air pollution effects on biodiversity and structure and functioning of terrestrial ecosystems; the introduction of metabolomics in ecology, the study of the mechanisms, function and effects of volatile organic compounds emissions by plants and ecosystems, the disentangling of biogeochemical processes involved in the carbon and nutrient cycles, or the development of science and policy for a sustainable planet, among many others. This work led to a critical understanding of how environment and ecology are centrally important in managing the global environmental crisis. Prof Penuelas has also introduced seminal concepts and tools in ecology like the “elemetome” or the “biogeochemical niche”, in omic sciences such as “ecometabolomics”, in remote sensing such as “photochemical reflectance index” or “water index”. He has coordinated groups of international scientists in the production of a series of influential papers on Ecology, Earth sciences, plant and animal sciences, agriculture, and the influences that human activities have on the biosphere. He also has an international reputation in other, diverse fields, such as molecular ecology, theoretical ecology, agriculture, food security, global human health, or the role of humans in precipitating global change and existential crisis during the Anthropocene. This expertise and impact is reflected in the number of Keynote and Plenary invitations in the most prestigious universities and research centres, the Prizes and Awards he has been awarded to, his H-index which is 147, and his ca. 111.000 citations.
