My research program is aimed at gaining insights into the processes underlying the evolutionary origin and maintenance of biological diversity with specific focus on the ecology, evolution and genomics of forest trees. Understanding these processes provides the necessary basis for the development of sound conservation and sustainable management strategies for forest and agricultural areas. Current research projects in my laboratory include studies in forest tree community assembly, population genetics and microbiomics of tropical and temperate forest trees and crop plants.
