Positions

Professor of Ecology and Tutor in Biological Sciences
Tutor for Graduates

Subject

Biological Sciences

Qualifications

MA (Oxford), PhD (Leeds)

Academic Background

I studied Biology at St. Hugh's College, Oxford.  My PhD was on the population ecology of butterflies at the University of Leeds. I was a postdoctoral researcher at Imperial College and The Natural History Museum before returning to the Zoology Department in Oxford in 2001. I have been Fellow and Tutor in Biology at Brasenose since October 2007.

Research Interests

I am a community ecologist and conservation biologist. My interest is in the processes that maintain, structure and threaten biodiversity, particularly in highly diverse tropical forest ecosystems. Further information is available on the Department of Zoology web site: www.zoo.ox.ac.uk/people/professor-owen-lewis

Teaching

I lecture and tutor ecological options in all three years of the Biological Sciences course, and run a third-year field course in Tropical Forest Ecology in Sabah, Malaysian Borneo. I also teach invertebrate and plant biology and quantitative methods (statistics).
