Professor and Canada Research Chair
Departments of Zoology and Botany
University of British Columbia
- David and Lucile Packard Fellow for Science and Engineering (1993-1998)
- Associate and Assistant Professor, University of Arizona (1990-2003)
- NSERC Postdoctoral Fellow, U. C. Berkeley (1988-1990)
- PhD, Harvard University (1988)
- BSc Zoology, University of Toronto (1980)
My research arose from a fascination with the diversity of forms and behaviours of jumping spiders, which led to systematics, which led to phylogenetic theory and computer programming. My work continues to be both empirical, on spiders, and theoretical, on the use of phylogeny in evolutionary inference.
