History and Philosophy of Biology
Richard Goldschmidt's Heresies
I am currently completing a biography of Goldschmidt's bad reputation as a biologist that contrasts different representations of his life and work.
Survival of the Luckiest: Perspectives on Random Drift in Evolutionary Biology
I am co-authoring a book with Roberta Millstein and Robert Skipper that puts genetic drift into historical and philosophical perspective.
History and Philosophy of Molecular Evolution
I have projects underway concerning model building and method selection in molecular evolution, especially with the rise of both DNA sequences and computerization.
History of Embryology in the Twentieth Century
I am currently researching the fate of embryologists who were forced to flee Germany. I am focusing on Hans Holtfreter's research on the mechanics of gastrulation and Viktor Hamburger's developmental genetics research on the creeper mutant.
