Dr. Bruederle's research interests include the evolution of species rich genera such as Carex (Cyperaceae), which comprises approximately 2000 species worldwide. He is interested specifically in the evolutionary mechanisms that facilitate speciation in this large genus. Additional interests include: plant systematics at and below the level of genus, population genetics and endemism, conservation genetics, and biogeography. He is also interested in the implementation, institutionalization, and assessment of undergraduate research.

Dr. Bruederle is currently collaborating with colleagues at the Canadian Museum of Nature and Universidad Pablo de Olavide on research addressing the bipolar distribution of certain Carex species. In addition, he is undertaking research funded by the US Fish & Wildlife addressing the systematics and conservation genetics of Penland's alpine fen mustard, a Colorado endemic that is federally listed as threatened. Recently completed research on the pollination biology of Degener's beardtongue, another Colorado endemic, is currently being summarized for publication.
