一、 简介：
赵天永，教授，博士生导师。1990年本科毕业于河北农业大学园艺系。1998年获中国农业大学作物遗传育种专业博士学位。1998至2011年曾在美国加州大学伯克利分校（U.C.Berkeley）和肯塔基大学（University of Kentucky）从事博士后研究并随后任职Scientist I、Scientist II。2011年3月起就职于西北农林科技大学,主要从事玉米抗逆分子生物学研究工作，发现了棉子糖是控制玉米耐旱耐热的关键因素，通过调控棉子糖代谢能够提高玉米的耐旱和耐热能力。主持国家转基因专项重点项目、国家自然基金面上项目和陕西省自然基金项目。目前承担本科生《分子生物学》英文教学工作以及博士生的《生命科学研究进展》课程。
