Timothy Walker

Lecturer in Plant Sciences (Somerville); Former Director of the University of Oxford Botanic Garden and Harcourt Arboretum
MA, MHort, FLS

I teach Biology at Somerville, and most of my teaching concerns plant biology because this is the interesting part of the subject.

In the first year the topics I cover include plant life histories including pollination, biological classification, the use of plants in medicine, the emergence of agriculture, and conservation.  In the second year I teach about plant adaptations (particularly those found in Mediterranean-type regions), ecology, and ethnobotany.  In the final year I run an option on species conservation and I teach on the Tenerife Field Trip.

Prior to coming Somerville I worked at the Oxford Botanical Gardens and Harcourt Arboretum for the best part of 34 years, the last 26 as Horti Praefectus (i.e. director).  My particular interests are plant conservation and the genus Euphorbia which is a fascinating group of 2000 species found all over the world.
