简要介绍：1) 碳氮和污染物在地下水和地表水交互带的水文生物地球化学过程
　　地下水与地表水交互带是流域生态系统的一个重要组成部分, 是化学物质在陆地和水体之间迁移转化的关键地带，也是地表和地下两个水体中生物群落之间的关键过渡带。交互带的水文和生物地球化学过程不但受生态环境和气候变化的影响，也受到人类活动(如灌溉、施肥、污水排放等)的直接或间接作用。如何描述和刻画地下水与地表水交互带中化学和生物地球化学过程，以及污染物的迁移转化是尚未解决的问题。在中国基金委群体(**)和面上基金(**)等项目支持下，本团队正在研究碳氮循环和As、Cr和氮等污染物在地下水和地表水交互带中的水文生物地球化学过程。
2)污染物在土壤和沉积物中的多尺度行为、机理和模拟
　　吸附/解吸、沉降/溶解，以及氧化/还原等土壤/水/污染物相互作用是控制金属和放射性核素的生物利用及其毒性的主要过程，这些作用还影响了污染物的扩散、迁移和持久性，以及影响污染修复技术所采用的方法、成本和效率。如何在天然和修复条件下，特别在复杂和非均质土壤和沉积物中精确预测土壤/水/污染物相互作用是当今环境科学和技术的一大重要难题。多年来刘崇炫教授团队在美国能源部多项环境修复科学和技术项目支持下，针对这一课题开展了深入和系统的研究：揭示出土壤/水/污染物相互作用的速率和程度随着时空尺度的增加呈现非线性的下降或上升，这种下降或上升随着土壤和沉积物的非均质性变化而变化的规律，建立了非均质和多尺度对地球化学和生物地球化学反应动力学影响的系统理论，开发了一系列数学模型来刻画金属和放射性核素在土壤和沉积物中的多尺度行为，并提出了具体的实验和理论相结合的方法去应用这些数学模型来预测土壤/水/污染物的多尺度相互作用。相关的研究工作在继续中。
3)微生物群落结构功能和水文生物地球化学过程的协同演化
　　在表生地质环境中，地下水化学成分的演化和微生物群落的结构和功能密不可分。微生物从地下环境中获取生存所需的养分和能量，促进微生物群落结构和功能的改变，同时也直接或间接造成地下水化学成分的变化和影响污染物迁移转化的途径。本研究团队侧重研究地下水生物地球化学过程和微生物群落结构功能间的协同演化。应用新一代测序技术，代谢组学和蛋白组学研究微生物群落的结构和功能、时空分布，结合现代色质谱分析仪器、微观成像和大数据处理技术研究微生物群落和功能和其环境间的相互作用关系，构建基于微生物群落功能的新一代生物地球化学反应动力学模型，为解决生态环境问题和开发经济有效的污染地下水生物修复技术提供理论支撑。
4)微生物的降解和固定技术
　　利用微生物进行原位降解或固定金属、放射性核素和有机污染物是当前经济有效的污染修复技术之一。设计并实施该修复技术的一大关键在于：构建生物地球化学动力学模型以有效预测微生物生长速率和程度、碳源和能量利用效率，以及微生物呼吸作用中对污染物的降解或固化速率和稳定性。本团队在多项美国能源部地下水污染修复科学和技术项目的支持下，在这一领域进行了长期深入研究，建立了多种微生物的生物地球化学动力学的模型，这些模型被广泛用于以微生物为主导的修复技术方面的理论和实践研究。
5)环境材料
　　在环境应用领域，纳米技术已经受到越来越多的关注，例如用于捕获并去除土壤，沉积物和地下水中的重金属和放射性核素。然而，在地下环境中应用纳米技术面临着一个重要挑战，即纳米材料的稳定性、保留时间、及其与污染物的相互作用程度。本团队在美国能源部、环保部和基金委的联合支持下正在开发各种环境材料。已经研发出一种新型纳米多孔材料，该材料具有极大的活性表面积 (ca 1000 m2/g)，能够有效的从废水和污染的地下水中捕获重金属和放射性核素。在此基础上，还发展了一项原位监测技术可以示踪地下环境中这种纳米多孔材料的迁移行为。
