Current Position
Visiting Fellow
Research Interests:
(i) The physiology of plants as affected
by global change (increasing temperature and atmospheric CO2 concentration).
At present, this research focuses on plants from subantarctic
islands (such as Heard Island and Macquarie Island) and from alpine
environments.
(ii) The nitrogen economy of plants and communities. In particular,
I am interested in nitrogen-photosynthesis relationships in leaves
as affected by their environment.
(iii) I still keep an interest in the stress physiology of plants,
namely in waterlogged and saline systems.
