目前从事的研究领域：
主要从事大气污染影响和控制有关的研究。研究重点为大气硫、氮和重金属沉降对土壤、水体和生态系统的影响，以及基于影响的大气污染物排放控制对策。揭示中国典型地区森林土壤酸化的重要过程与机理，提出基于影响的酸沉降控制决策理论与方法，建立临界负荷的新理论与新方法，系统完成中国硫沉降和氮沉降临界负荷区划。相关成果获得国家科技进步二等奖两项，教育部科技进步一等奖两项和自然科学二等奖一项。完成学术著作两部，其中之一获得中国图书奖，此外还在国内外学术刊物和会议上发表了论文70多篇（其中SCI收录30多篇），获得国家发明专利授权三项。2003年全国优秀博士学位论文获得者，2005年入选教育部“新世纪优秀人才支持计划”。
