從1997年4月起在德國工作和學習。在德國漢堡工業大學攻讀博士期間，主要從事生態污水系統的研究，特別是分流污水處理技術和污水回用技術的研究。並發表德文版專著一本 "Grauwasserbehandlung und -wiederverwendung" ISBN 3-930400-63-4, 參編由國際水協發行的英文版專著一本 "Water in China" ISBN 1843395010, 而且發表有多篇相關英文和中文論文。2003年6月 - 2004年6月，在德國埃森大學城市水管理研究所工作。作為研究所研究員，本人參加了中德合作的大型科技項目，該項目的題目為： 可持續性發展的水管理方法的研究 - 城市雨洪控制和雨水的利用。德國埃森大學作為該項目德方總負責單位，申請人作為埃森大學第二項目負責人參加了該項目的部分工作，並發表了會議論文、雜誌論文，撰寫專著2本（待出版）。該項目科研經費總額超過六千萬人民幣。
2004年十月份從德國回國工作以來，指導碩士研究生已畢業17名，外國留學生已畢業1名。目前總計帶有十九位碩士研究生，同時承擔了一名外國留學生的培養工作和指導二名博士生的工作。科研方面承擔了多項科研任務，包括聯合國兒童基金會（UNICEF）的分散污水處理項目、歐盟資助的生態衛生技術推廣項目、中國-瑞典合作鄂爾多斯生態衛生項目、江蘇省崑山市農村污水處理項目、北京科技大學422人才基金資助項目《豎向流植物濾池處理污水的研究》、教育部留學回國科研項目《豎向流植物濾池處理污水最佳化技術的研究》、德國IHC公司資助項目《北京科技大學學生公寓污水處理和回用工程研究》、深圳市規劃局委託項目《深圳市居住區小區雨水利用規劃指導》、建設部委託的項目《人工濕地處理污水技術導則》等科研項目。2006年9月由我校環境工程系與其他兄弟單位合辦並在我校召開的2006年北京國際環境技術研討會成功地舉辦，引起各界廣泛關注，其會議論文集已被國際著名的ISTP全集收錄，本人是會議的主要組織者和會議論文集第一編著者。過去五年申請人發表了二十餘篇論文，其中有11篇被SCI、EI和ISTP收錄，申請專利5項。
