本人有近十年的海外留学及工作经历，主要从事微生物资源开发利用水产养殖生态相关领域研究，具体偏向水产病害生物/生态防治，水产益生菌的益生作用机制，微生物生态与微生态制剂在水产养殖中应用等。研究成果主要服务于生态养殖产业的绿色、健康及可持续发展，即保护水域生态环境、合理利用资源和提高经济效益等。近期发表第一作者/通讯作者SCI论文二十余篇。

近年承担生科院生态学专业及国际学院本科课程5门（微生物学、生态学专业英语、生物资源与利用、分子微生物学、环境科学概论），其中全英课程4门。多门课程在学院本科课程质量评估结果中位列前10%。曾获“暨南大学首届新任教师教学竞赛二等奖”、“暨南大学第六届本科课程全英语教学竞赛二等奖”、“暨南大学本科教学校长奖”、“生命科学技术学院2019年度本科教学突出个人贡献奖”等多项荣誉。

曾担任生态学专业2015级本科班班主任，在2018、2019年连续获得“优秀班主任”荣誉称号。
