在英国诺丁汉大学Grierson教授(英皇家学会院士)实验室工作期间(94-95)，发现了转基因反向重复基因顺序引起高频高强度基因沉默，受到学术界广泛重视，包括被《Cell》、《Plant Cell》等引用。之后又首次阐明了siRNA与靶基因mRNA降解的直接关系，论文被收入Faculty of 1000并被《Science》和《Genes and Development》等重要杂志引用。发表的SCI论文总引用次数超过350以上。
自2010年回国以来,从事谷子食味品质形成机理研究,对米色、香味和口感方面从基因组学和代谢组学角度进行分析，以期发现相关性状的重要基因并分子标记，开展分子育种，培育品质优异的谷子品种。
