Academic staff

Dr Charles Warren

Charlie Warren has a bachelors degree from the University of Tasmania, a PhD from the University of Western Australia and has recently obtained formal qualifications in university teaching and supervision of graduate students. Charlie has worked in Canada and France and maintains active overeas research links (e.g. with France).

Charlie's main research interests are:

• Diffusion of CO₂ within leaves
• Photosynthesis and the C cycle
• The ecosystem N cycle and N uptake by plants
• Plant responses to temporally variable water and nutrients

Charlie is willing to take on keen PhD and honours students. He will entertain any project that fits within his area of expertise and can be accommodated by the School’s facilities. Interested students should approach Charlie with details of undergraduate grades and areas of interest.

Technical staff

Captain Eppi

Captain Eppi has recently joined the lab as a research assistant. He has a keen interest in the ecophysiology of plants and was awarded first class honours for his thesis "Measuring hydraulic properties of xylem via the centrifugal technique". Eppi is using his time as a research assistant to decide whether he should pursue a PhD.

The Captain is indispensable because he is working on a large number of projects and methods. First up he will be extracting ¹⁵N-labelled proteins from leaves of spinach. The _¹⁵N-labelled proteins will be used to "feed" to other plants. Eppi will extract proteins with molecular weight cut-off filters and our new refrigerated centrifuge. Once this task is finished Captain Eppi will be spending a lot of time preparing and centrifuging extracts of plant material. These extracts will be used for measuring primary metabolites.

Captain Eppi has many interests outside of the laboratory. Acacia and Casuarina are his two favourite genera and he spends much of his spare time nurturing his garden of Acacia and Casuarina.
