主要研究兴趣为密码学与信息安全，特别是格密码学及其应用。与合作者一起，致力于研究格密码实用化中的安全分析与设计。
2013年毕业于华中科技大学并获博士学位，期间获国家奖学金及学校优秀论文奖等奖励。
2014年入选中国地质大学（武汉）“摇篮计划”，2016年入选“地大学者”。
2014年6月至8月作为访问学者访问新加坡科技设计大学；
2014年11月至2016年11月受日本学术振兴会（JSPS）选拔资助，在日本九州大学任JSPS博士后研究员两年。
先后主持国家自然科学基金青年项目(已结题)一项和面上项目两项（已结题一项）。
兴趣是最好的老师，欢迎对信息安全有兴趣有热情的同学与我联系，chengchi@cug.edu.cn。尤其欢迎参加过信安大赛、ACM比赛的同学联系。
