Nicholas is a senior lecturer in evolutionary biology and paleontology at the University of Bath. He is interested in how and why the world is the way it is and studies dinosaurs, among other things—pterosaurs, fossil birds, lizards and snakes. He is also interested in understanding macroevolution—large-scale evolutionary patterns and processes. Stuff like the evolution of organisms and ecosystems over millions and billions of years, the evolution of complex adaptations like bird flight, and the snake body plan. He is particularly interested in the idea that macroevolution is more than just lots of microevolution—that over long periods of time, at large scales, and in the evolution of complex structures, different dynamics come into play. That over time, the processes of evolution itself have evolved.
