What steers the evolution of fungi, and how do evolving fungi affect our environment? Christopher is tackling questions in evolutionary biology using the latest genomic tools to understand how our world is shaped by fungi. The flow of genes between or within a species can drastically affect its evolutionary trajectory, and Christopher is studying how changes in gene flow can change the course of evolution. Climate change is also altering the course of evolution, and Christopher is collaborating with climate modelers to understand how the decomposers of tomorrow will further alter Earth’s climate. These questions are fundamental to understanding patterns of diversity across all life, as well as the impact evolution has on our environment.
