BSc Mass., PhD McG.
I spent my early years in the United States of America, mainly in the small New England state of Vermont, renowned for the beauty of its autumn foliage, the purity of its snow and the sweetness of its maple syrup. I completed my Bachelor of Science degree in Biochemistry at the University of Massachusetts, Amherst (U.S.A.). I then left the U.S. for Montreal, Canada to undertake a PhD at McGill University. My PhD experience sparked my interest in mitochondrial biogenesis, an area I continue to research at UWA. After completing my PhD in 1989, overjoyed at finishing the degree but greatly saddened by the prospect of leaving beautiful, cosmopolitan Montreal, I moved to Australia with the view of staying for a 2 year post-doctoral experience. I have been here ever since, enjoying the natural beauty of the place and the friendliness of the people. I held post-doctoral research positions at Monash University, Queensland University of Technology, The Australian National University and Macquarie University. Before taking up my position as Lecturer in Plant Biology at UWA in 2003, I held lecturing posts in the Department of Biochemistry and Molecular Biology, ANU (1999) and the School of Science, Food and Horticulture, University of Western Sydney (2001 – 2002). I have always enjoyed opportunities to work with Australian and international research students at both the undergraduate and postgraduate levels. Over the years, I have been actively involved in the supervision of many Honours and postgraduate research students. All these students successfully finished their research degrees and most are still directly involved in scientific research. I remain very interested in plant mitochondrial biogenesis, and have more recently branched into the area of plant phosphate nutrition, as you can read by following the link to my Profile page. In particular, I am amazed at the ability of Australian native plants, especially in southwestern Australia, to survive on soils that are the most nutrient impoverished on earth.

I enjoy interacting with students at all levels, so I teach in 1st, 2nd and 3rd level units and supervise 4th-year Honours, Masters and PhD students. In the level 1 unit Frontiers in Biology (BIOL1130), I teach aspects of biological diversity, cell structure and function, and biochemistry. At 2nd level, I lecture on the physiological impacts of photosynthesis and respiration (oxygen consumption) on plants in Plant Physiology: Plants in Action (PLNT2201). In the level 3 unit Plant Physiological Ecology (PLNT3301), I teach about the responses of plants to abiotic stress and the establishment of plant symbioses. Good communication skills are invaluable to good science. I teach these skills in the level 1 unit Science, Society and Communication (SCIE1103) and in level 4 and 5 research units.

Current projects
I am happy to supervise domestic and international students at the Honours, Masters and PhD levels in any of my research areas. My group uses a number of targeted and non-targeted approaches to understand the gene regulatory pathways that control phosphorus nutrition and changes to mitochondrial protein gene expression during plant development and under various environmental conditions. Several projects in collaboration with Prof Hans Lambers (Plant Biology) investigate the molecular physiological adaptations in plants that regulate the acquisition of phosphate from the environment and that allow plants to survive on highly weathered soils that contain very little phosphate, an essential nutrient. Of particular interest is the mechanism that underlies the delayed greening of leaves in several native species of Proteaceae.
