研究方向：

乙型肝炎病毒（HBV）感染，特别是慢性感染，可引起慢性乙型肝炎、肝硬化和肝癌等严重后果，是重大的公共卫生问题，2016年世界卫生组织提出了“2030年消除病毒性肝炎的威胁”的目标。目前HBV感染可预防、可诊断、可治疗，但慢性感染难以彻底治愈。

HBV是易变异的病毒，我们以HBV变异及其生物学和临床意义为研究方向，应用病毒学、分子生物学和免疫学等技术方法，结合临床病例，开展基础和临床相结合的研究。从临床标本分析入手，发现和鉴定有意义的病毒突变类型，并在体外研究突变株对病毒生物学特性、耐药性、致病性、免疫逃逸等特性的影响和机制，已发表一系列相关研究论文，曾获得秦皇岛市科技进步一等奖、河北省科学技术进步奖三等奖、北京大学基础医学院SCI论文引用奖和优秀SCI论文奖等奖励。
