主要从事PRRSV流行病学与遗传变异机制及新型基因工程疫苗研究，攻读博士学位期间，主要获得了以下研究进展: （1）持续跟踪PRRSV流行变异情况并探究其机制，分离多种优势PRRSV流行毒株；（2）利用反向遗传操作技术建立了HP-PRRSV、类NADC30 PRRSV、疫苗毒株MLV PRRSV等多种PRRSV毒株感染性克隆平台；（3）构建了类NADC30 PRRSV和HP-PRRSV重组毒株，其对两种PRRSV均有较好的保护效果。迄今，以第一作者在《Virologica Sinica》《Microbial pathogenesis》和《Archives of virology》期刊发表SCI论文3篇，在《畜牧兽医学报》和《中国兽医学报》期刊发表核心论文2篇，曾获“中国微生物学会兽医微生物学专业委员会暨中国畜牧兽医学会生物制品学分会学术论坛优秀论文”等奖励。
