(1) 药物质量研究与安全性评价
(2) 基于金属组学的药物作用机制研究

1、科研项目
（1）国家自然科学基金青年基金项目，81903911，基于汞元素金属组学的朱砂中枢神经毒性机制研究，2020-01-01 至 2022-12-31，21万元，在研，主持
（2）江苏省自然科学基金青年项目，BK20190556，基于金属组学的朱砂中枢神经毒性研究，2019-07 至 2022-06，20万元，已结题，主持
（3）中国博士后科学基金面上资助，2017M621885，含朱砂中成药柏子养心丸基于汞形态的毒性与安全性研究，2017-09至2020-06，5万元，已结题，主持
2、代表性科研成果
（1）微量杂质分析是药物质量控制的重点与难点之一，基于高分辨质谱等现代分析技术，摸索并形成了成熟的药物杂质研究策略，现已成功帮助企业完成氟马西尼、佐匹克隆等多个药物品种原料药及制剂的生产工艺优化与质量提升。
（2）针对传统中药朱砂（HgS）的安全性与质量问题，基于金属组学研究，探索其物质基础、作用机制及药物相互作用。首次发现朱砂在生物体内的汞元素形态转化，明确了其物质基础；并将汞元素形态引入到含朱砂中药的质量控制之中，确立了与朱砂相关的关键制剂质量控制点，为朱砂及含朱砂制剂的质量控制和合理使用提供宝贵的参考依据。
