I am a historian of early science and medicine with a research specialty in ideas about the inner workings of nature that were developed in medieval and early modern Europe. In A Philosophical Path for Paracelsian Medicine and several articles I explore elements of a biological philosophy developed by the followers of the German iconoclastic physician and lay preacher, Theophrastus Paracelsus. I am particularly interested in the manifold connections between medicine, science, pharmacy, and religion in early thought. Recently I have undertaken research in the history of biological rhythms studies (chronobiology) and am promoting this area of research among my colleagues and developing an on-line research database of related materials (if interested, please send e-mail).I received the B.S., M.A., and Ph.D. degrees in the History of Science at the University of Wisconsin.
