Workplaces:	University of British Columbia, Beaty Biodiversity Museum, University of Arizona, U. C. Berkeley
Alma Mater:	University of Toronto, Harvard University

Wayne Paul Maddison, is a professor and Canada Research Chair in Biodiversity at the departments of zoology and botany at the University of British Columbia,^[1] and the Director of the Spencer Entomological Collection at the Beaty Biodiversity Museum.^[4]

His research concerns the phylogeny, biodiversity, and evolution of jumping spiders (Salticidae), of which he has discovered new species and genera.

He has also done research in phylogenetic theory, developing and perfecting various methods used in comparative biology, such as character state inference in internal nodes through maximum parsimony,^[5] squared-change parsimony,^[6] or character correlation through the concentrated changes test^[7] or pairwise comparisons.^[8] In collaboration with David R. Maddison, he worked on the Mesquite open-source phylogeny software, the MacClade program, and the Tree of Life Web Project.^[1]

His research has led him to discover new species of jumping spiders in Sarawak and Papua New Guinea.
