蔡永久，男，1985年生，安徽六安人。2006年获安徽大学环境科学专业学士学位，2011年获中国科学院南京地理与湖泊研究所自然地理学专业博士学位，同年留所工作，历任助理研究员，副研究员。主要从事流域水生态健康评价、多时空尺度淡水生物多样性格局及驱动机制、底栖生态学等方面研究。 

主持国家自然科学基金3项、江苏省自然科学基金1项，参与水专项、973计划、科技部基础性工作专项等多项国家级科研项目。主持和参与的项目主要有：国家自然科学基金“鄱阳湖洪泛湿地螺类群落对季节性干旱加剧的响应机制”、“气候变暖与富营养化双重作用下浅水湖泊螺类的响应及其机理”、水专项“流域水生态保护目标制定技术集成”、中科院STS项目“长江经济带岸线资源调查与评估”、中科院先导专项“长江经济带干流典型湖泊水生态修复与综合调控”、江苏省水利厅项目“江苏省湖泊健康评价”等。 

围绕流域水生态保护与管理的需求，系统开展了多空间尺度淡水底栖多样性及驱动机制研究，探究了流域底栖生物空间格局及对环境压力的响应关系，发展了流域水生态状态评价指标体系构建与保护目标制定技术方法。目前以第一/通讯作者发表学术论文30余篇，其中SCI论文20余篇，包括Limnology and Oceanography, Diversity and Distributions, Science of the Total Environment, Ecological Indicators、湖泊科学等生态环境领域知名期刊，参与制定江苏省地方标准2项《湖泊水生态监测规范（DB 32/T 3202-2017）》、《生态河湖状况评价规范（DB 32/T 3674-2019）》，前四作者出版专著5部。获2021年度长江科学技术奖一等奖（排名第5），入选2020年中科院青年创新促进会会员。
