Professor Owen Lewis
Professor of Ecology and Tutor in Biology
MA (Oxford), PhD (Leeds)
I grew up in Bridgend, South Wales where I attended Brynteg School. I studied Biological Sciences at St. Hugh's College, Oxford and then did a PhD on the population ecology of butterflies at the University of Leeds. I worked as a postdoctoral researcher at Imperial College, The Natural History Museum (London) and the Smithsonian Tropical Research Institute (Panama) before returning to the Zoology Department in Oxford in 2001. I have been Fellow and Tutor in Biology at Brasenose since October 2007.
I am a community ecologist and conservation biologist, studying the processes that maintain, structure and threaten biodiversity, particularly in highly diverse tropical rainforest ecosystems. I have a particular fondness for insects. Further information is available on the Department of Zoology web site: www.zoo.ox.ac.uk/people/professor-owen-lewis, from my research group pages at https://communityecology.zoo.ox.ac.uk/ or you can follow me on Twitter (@OwenTLewis).
I teach in all years of the Biology course, mostly ecology, entomology and conservation biology, and supervise students for 4th year research projects. Each year I also run a field course in Tropical Forest Ecology in Sabah, Malaysian Borneo.
