I'm a paleontologist and evolutionary biologist from Kodiak, Alaska, interested in how and why the world is the way it is. I study dinosaurs, among other things like pterosaurs and fossil birds, lizards, and snakes. I'm interested in understanding macroevolution- large-scale evolutionary patterns and processes. That includes 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. I'm 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.
