Graduate Environmental and Geo-Environmental Society

NEU Student NEWEA / WEF Chapter

Faculty - Students - Research - Publications - Presentations - Home


The purpose of the NU GEGES is to improve the quality of the graduate environmental and geo-environmental experience at Northeastern University. Seminars, workshops, field trips, and other events will be organized to introduce and further the knowledge of various topics in environmental and geo-environmental fields. It will provide a forum for networking with graduate students, faculty, professionals and societies in the environmental and geo-environmental fields and leadership to younger students interested in joining the environmental program.


GEGES celebrated the first meeting of the 2009-2010 academic year. A new Board of Directors was elected and new GEGES seminar dates were determined (see below).

-President: Xiaodan Ruan

-Vice-President: Ce Gao

-Treasurer: Lei Liu

GEGES has been approved of $3000 for
Seminars and Study Tours by the finance committee of GPSA
