My Work

I am a research scientist at CSIRO Plant Industry working on grapevine physiology, primarily around water use. Prior to this I worked as a post-doctoral fellow at RSBS, part of the Australian National University, for five years.

There is not yet consensus on whether nutrient deficiency affects the response of plants and ecosystems to elevated CO2, but legumes are of particular interest due to their high tissue nitrogen content and ability to fix atmospheric N2. Grazed pasture in southern Australia covers over 60 million ha and accounts for approx. 60% of total Australian biological nitrogen fixation (BNF). Furthermore, BNF provides the largest flux of N into Australian soils.

From October 1993 to June 1997 I studied for a PhD at The Nottingham Trent University. The title of my thesis was 'The Accumulation of Chlorophylls and Glycoalkaloids in Stored Tubers'.

Many of you will have noticed that when you've had your potatoes lying around for a bit they start to go green. This is due to the formation of chlorophyll (the green pigment found in plants) which is both tasteless and harmless. So why are greened potatoes considered inedible?

From April 1998 to March 2001 I worked as a post-doc at The University of York. The project was to follow up results from a previous TIGER project which indicated that root growth and respiration may be determined by received radiation flux rather than soil temperature as commonly thought. The aim of my work was initially to provide further evidence of this by using a combined controlled environment and field study approach. Subsequently, a possible role of nitrogen was to be examined and a model parameterised. The following is adapted from the final report to the funding body.


So. Rather than leave everything to Facebook and all the anoyances that entails I have ditched my account and turned my old site into a blog. There are some rather old overviews of my past work, a few random pages on my interests and, by default, whatever random stuff I've felt like posting.
