　　报告人简介：

　　Dr. Hahn received a B.S. in chemistry and a B.A. in Independent Studies in 1974 from the University of Oregon and his Ph.D. in biochemistry in 1981 from the University of Colorado. A postdoctoral research associate appointment at the University of Wisconsin-Madison in plant pathology followed, after which Dr. Hahn went to the Albert-Ludwigs-Universi?t (Freiburg, Germany) with the support of an Alexander-von-Humboldt stipend. Following another post-doctoral research associate appointment at the Salk Institute (San Diego, CA), Dr. Hahn joined the CCRC in July 1986.

　　His laboratory studies the cell biology and biosynthesis of plant cell walls. Plant cell walls play major roles in the biology of plants. Examples of these roles include controlling the growth and shape of plant cells, tissues, organs, and ultimately the entire plant, regulating the movement of nutrients and signals within the apoplast and toward the plasma membrane, serving as the first line of defense against path-ogens and environmental stresses, and acting as a source of signaling molecules important in plant development and defense. Plant cell walls are also the principal component of plant biomass, which has become a focal point in the search for alternative and renewable sources of energy (biofuels).

　　Micheal G. Hahn教授的研究领域主要是细胞壁多糖的合成调控机理。他领导的实验室在半纤维生物合成途径研究方面取得了一系列重要突破，解析了GATL和FUT基因家族在半纤维素合成中的作用机制。开发了170余种多糖单克隆抗体，用于细胞壁多糖的准确和灵敏检测，并提供给世界各国相关科研工作者使用，现已成为国际上该领域颇有知名度的专家。
