Qualifications
and Appointments
B.Sc. in Plant Physiology and Biochemistry, China Agricultural
University (1989); M.Sc. in Biophysics and Microbiology, Graduate
School of Chinese Academy of Agricultural Sciences (1994); Ph.D.
in Plant Physiology, Stockholm University (2005, see Dissertation).
Research Associate in Department of Biotechnology, Institute
for Application of Atomic Energy, Chinese Academy of Agricultural
Sciences (1994-2000), and Visiting Scientist at Environmental
Technology-VITO (Flemish Institute for Technological research),
MOL, Belgium (1998-1999). Research Fellow in School of Botany,
The University of Melbourne (Aug. 2005 - ).
Research
Interests
Plants-microbe interactions, physiology of heavy metals (mainly
Co, Ni, Cu, Cd and Hg) accumulation by plants, and use of the
plants for phytoremediation of contaminated soils with heavy
metals and organics.
Current
Research Activities
Dr Wang mainly work for an ARC-Discovery project 'Physiological
and biochemical dissection of cobalt accumulation by plants'
in collaboration with Prof
Andrew Smith at Department of Plant Sciences, Oxford University,
UK. The main objectives of the project are 1). Determine the
difference in Co accumulation and tolerance among Australian
common pastures; 2). Determine the tolerance and accumulation
capacity for Co in hyperaccumulating plants; 3). Determine if
Co is an essential element for some Co-hyperaccumulators; 4).Determine
the detail growth responses to Co by measuring ions uptake,
water transpiration, photosynthesis, Chlorophyll content, tissue
and cell structure, antioxidant enzymes, and biomass; 5). Identify
and characterize Co-binding ligands in the xylem sap and cells;
6).Determine the distribution of Co sequestered in the shoots
(and root nodules) at both the organ and cellular level by using
microPIXE (in ANSTO, Sydney) and nanoSIMS (in Oxford University);
7). Identify and characterize metabolites and enzymes in relation
with Co uptake and accumulation by using Metabolomics and Proteomics.
These finding will support strategies for phytoextraction of
the valuable metal Co from contaminated land and the development
of Co-enriched fodder crops.
