Job Title: Professor of Biological Sciences
Employer: Dept of Biological Sciences, University of Alberta
Further Education: Washington & Jefferson College (B.Sc.), University of Vermont (M.Sc.), University of British Columbia (Ph.D.).
Geographic focus of research: Alberta, British Columbia, Mexico, Kenya, Indonesia
Brief synopsis of current research:
My students and I work in three general areas bridging evolution and ecology:
1) structure and dynamics of arthropod populations,
2) integration of communities, especially those under anthropogenic influence and
3) the nature and evolution of arthropod species and their life-histories.
Our research program couples broad scientific objectives with the promise of shorter term applications in management and conservation of forests and wetlands. Work generally proceeds from a strong natural history base to develop experimental approaches to questions that apply to particular taxa. Generalization follows after common threads are discovered and confirmed experimentally.

Nothing is half so much fun as splashing around in a pond or stream along with the other creatures that live there. Of course, water is touted to be the environmental problem of the coming few decades.
