Casey Helgeson is a graduate student and associate lecturer in the department of Philosophy at the University of Wisconsin - Madison, and a Graduate Research Fellow of the (United States) National Science Foundation. He received his undergraduate degree in mathematics in 1997 from the University of Wisconsin, and taught secondary school mathematics in Budapest, Hungary before returning to academia in 2005 to study philosophy. His research interests include evidence and confirmation, unification, rationalism and empiricism, the Whewell/Mill debate, concept change in science, conceptual disputes within evolutionary biology, phylogenetic inference and biological taxonomy, and the evidence for the fundamental theses of evolution. He is writing a dissertation about the epistemology of data partitions in a family of biological inference problems from pre-Darwinian taxonomy to contemporary systematics, biogeography, and ecology.
