I was born in Saskatchewan and spent my childhood in Chatham, London and Markham, Ontario. A graduate of the University of Toronto Schools, I received my B.Sc. with highest distinction from the University of Toronto in 1981. I subsequently attended the University of Tübingen as a German Academic Exchange Fellow in Biological Cybernetics, returning to Toronto in 1982 to complete my Ph.D.  in insect sensory physiology with Prof. J.J.B. Smith at the Department of Zoology. From 1987 to 1988 I was a NATO Postdoctoral Fellow at Wageningen Agricultural University in the Netherlands, where I studied the use of natural enemies to control plant pests under Prof. J. van Lenteren.


In 1988 I was hired as an assistant professor of insect physiology in the Department of Environmental Biology at the University of Guelph. Since my appointment I have taught courses in Biological Control, Natural Product Chemistry and Insecticide Bioactivity and conducted research in insect nutritional and sensory physiology, pest management, computational chemistry and spider ecology.

In 1997 I co-founded Nanodesign Inc. a drug discovery company based on novel approaches to the computational design of biologically active molecules. From 1997 to 2003 I was Vice President of Research at Nanodesign leading an interdisciplinary research team designing and developing novel anticancer compounds. The  Dibenzo[c]chromen-6-one derivatives invented at Nanodesign, including Palomid 529, are novel dual inhibitors of mTOR and interfere with cell proliferation and angiogenesis (blood vessel formation) (Cancer Res. 68(22):9551-7). They are currently under development by Paloma Pharmaceuticals Inc. as potential anticancer (Br. J. Cancer. 100(6):932-40) and keloid disease (Am. J. Pathol. 181(5):1642-58) therapies and have demonstrated positive effects in the treatment of macular degeneration in Phase II human clinical trials.

In 2004 I returned full-time to the University of Guelph and in September 2009 I was appointed Associate Dean (Academic) of the Ontario Agricultural College. Since 2010 I have led the redesign of the Bachelor of Science in Environmental Science, the Bachelor of Science in Agriculture, the Bachelor of Bio-Resource Management and the Associate Diploma in Agriculture. In June 2013 I received the John Bell Award from the Senate of the University of Guelph recognizing outstanding contributions to university education.

I am currently conducting research on collembolan ecotoxicology and spiders in agroecosystems.
