主要从事污染场地重金属及有机污染物迁移、转化机理，污染场地修复技术研发，同步辐射技术在污染环境修复中的应用等研究。主要研究领域是重金属和有机物污染场地修复，涉及研究方向包括：

1）结合污染场地的水文地质情况，研究重金属及有机物在场地(土壤，底泥，地下水，地表水)的迁移机理；

2）应用同步辐射技术研究污染场地中重金属的迁移转化机理；

3）开展相关的污染场地修复技术研究。

4)  应用地球化学模型模拟污染物在包气带及含水层介质中的迁移转化

其在加拿大滑铁卢大学的研究成果被美国国家环保局报道；基于其所在课题组及刘鹏的研究成果，美国一汞污染场地的修复工作正在进行中。近五年主持参与水体与土壤污染控制与治理科技重大专项子课题等项目7项，其中进行的汞污染底泥的研究成果，被应用于美国一汞污染场地的修复；以第一或通讯作者在Analytical Chemistry, Science of the Total Environment, Journal of Hazardous Materials等国际期刊发表SCI检索论文14篇。曾获得滑铁卢大学A类博士论文及优秀博士论文奖，湖北省“楚天学子”和中国地质大学“地大学者”荣誉称号。

Peng Liu, Ph.D, professor, born in 1981 at Zibo City, Shandong Province. My research focuses on the remediation of heavy metals and organics contaminated sites. His current research includes: 1) study of transport mechanisms of heavy metal and organic contaminants in combination with the hydrogeological conditions of the site; 2) study of transformation mechanisms (geochemical processes) of heavy metals in the contaminated site using synchrotron-related techniques; 3) development and investigation of current and novel remediation technologies for the contaminated sites. Based on the results from the research group I was in and my research at the University of Waterloo (Canada), the remediation of a mercury-contaminated site in the United States is ongoing.
