Organized by the association of Chinese American Professors in Environmental Engineering and Science (CAPEES) with the collaboration of the Government Affair Committee (GAC) of AEESP, this workshop aims to provide a forum for discussion on international collaboration between US scholars and international scholars/institutions. Many environmental challenges, such climate change, pollutions, and biodiversity, require collaborative efforts toward global solutions. However, international collaborations across many disciplines are facing growing challenges. This workshop will cover opportunities and challenges of international collaborations on addressing global environmental issues. CAPEES and GAC plan to invite speakers and panelists from academia, university administration, and federal funding agencies to share their knowledge and insights on maintaining and promoting healthy international collaboration within compliance. Organizers: Shihong Lin, Vanderbilt University; Xing Xie, Georgia Tech; Tiezheng Tong, Colorado State University; Yang Yang, Clarkson University; Shouliang Yi, National Energy Technology Lab; Zhenyu Tian, Northeastern University; Jingqiu Liao, Virginia Tech
