简历:

  1989年沈阳理工大学本科毕业;19994月获工学博士学位(大连理工大学和中科院金属研究所联合培养)。攻读博士学位期间研究金属间化合物的强韧化机理。2000-2003年连续在韩国浦项科技大学(Pohang University of Science and Technology)、以色列本-古里安大学(Ben Gurion University)、法国格勒诺布尔国家理工学院(Institute of National Polytechnic of Grenoble, GPM2实验室)参与或负责镁合金材料及其制备成形过程的相关基础研究。2003年回国正式受聘为中国科学院“百人计划”,负责组建“镁基轻质材料及其应用”创新课题组;已负责 863”计划,国家自然科学基金,“973”计划,科工局设置,美国波音公司,美国通用汽车公司,重大航天工程等委托的镁合金领域项目二十多项。课题组已与德国、澳大利亚、美国、加拿大、日本、以色列、韩国等国际著名的镁合金研发机构建立了较为深入交流合作。2008-2014年间,SCI收录镁合金领域的学术论文100余篇,总被引超过1000次;已申请发明专利18项(含美国专利2项),其中已授权专利13项(含美国专利一项)。
