speaker introduction:
zhouyouping is an associate professor at the department of marine science and engineering, southern university of science and technology (sust). he received his ph.d. in environmental geosciences from the australian national university (anu) in 2005. he has exploited the small differences in isotopic abundances and abundance ratios of elements (c, h, o, n, s) present in natural (organic) molecules and specific sites within molecules to reconstruct elemental and material sources, synthesis and metabolic pathways, transport and transformation, and environmental and climate information, and to develop new frontiers of application of natural abundance isotopes in human nutrition, health, and disease diagnosis, and metabolic pathway analysis of key biochemical molecules. in recent years, his team in china has developed a number of new isotopic methods, such as (1) the intramolecularly specific o isotope analysis of glucose at the center of metabolism; (2) the intramolecularly specific o isotope analysis of lignin, which carries important plant physiological and climatic information; (3) an ultra-sensitive simultaneous n and o isotope analysis method for nitrate and nitrite with important environmental and health indications; (4) an intramolecular site-specific c isotope analysis method for fatty acids with important biochemical and biogeochemical implications. his research has been funded by the national natural science foundation under the "original exploration program" and "surface program". his original results have been published in analytical chemistry, plant, cell and environment, rapid communications in mass spectrometry, phytochemistry, and organic geochemistry.
