As Director of the Department of Coevolution of Land Use and Urbanisation, Patrick is committed to pioneering and applying multidisciplinary approaches to studying long-term relationships of our species and the Earth system, including research across the latitudinal tropics. This includes combining state-of-the-art approaches in field- and lab-based archaeological science, remote sensing, palaeoecology, history, computational archaeology, and land use modelling. In 2021, Patrick was awarded the Heinz Maier Leibniz Prize, the top award for early career investigators in Germany and the first time that it has been awarded to an archaeologist and in 2024, he received the Thuringian Research Prize from the Thuringian Ministry of Economics, Science, and Digital Society for fundamental research. As part of his aims to make his work accessible to the public, Patrick also wrote the popular book ‘Jungle: How Tropical Forests Shaped the World and Us’ published by Penguin/Viking Random House in 2021.
