I am a historian and philosopher of science interested in a bunch of topics at the intersection of the earth and life sciences. Some of the things that excite me are: problematic fossils, obsolete tectonic theories, Stephen Jay Gould, nineteenth century American geology, "uniformitarianism," and studies of early animal evolution. Dislikes include smugness, the word "curated," and AI (an environmentally disastrous technology whose meaningful consequences are nearly all bad).

I'm currently a postdoc at the University of Copenhagen working on the project Human Variables in Biodiversity Assessment (PI Joeri Witteveen). I'm also writing a book, which is a history of controversy about the Cambrian Period— think the "Cambrian explosion" and all that. In my spare time, I maintain Extinct: The Philosophy of Palaeontology Blog, where I write the "Problematica" essay series. You can find a full archive of this series by navigating to the "Problematica" tab, above.
