刘艳，女，1971年10月出生，中国农业科学院植物保护研究所研究员，博士生导师。

1994年获沈阳农业大学植物保护专业学士学位，同年7月进入中国农业科学院植物保护研究所从事科研工作至今，在职期间获植物病理学硕士和博士学位。

长期从事小麦病毒病害基础研究，先后主持国家自然科学基金面上项目2项，并作为科技骨干承担国家自然科学基金中挪国际合作项目、国家重点研发计划中捷国际合作项目、粮食丰产科技创新专项、公益性行业科技专项、转基因重大委托项目等项目（课题）10余项。近年来在小麦病毒的病害流行监测、病毒致病机理、介体昆虫传毒机制、抗源筛选以及防控技术体系构建等方面的研究中开展了大量原创性工作。并与国际同行专家建立了良好的合作关系,多次赴德国、捷克等国家开展合作研究。相关研究已在国内外学术期刊上发表论文60余篇，其中被SCI源期刊收录论文35篇；以第一发明人获授权国家发明专利7项，制定行业标准1项，参编著作1部；获得农业部中华农业技术二等奖（第二完成人）、中国农科院科学技术成果一等奖（第二完成人）、北京市科技进步三等奖（第四完成人）以及中国植保学会科技一等奖（第五完成人）等多项科技成果奖励。目前主要研究方向为：1）小麦病毒致病机理；2）小麦病毒与介体昆虫互作机制；3）小麦病毒流行监测预警与新病毒鉴定。
