Researchers from China's Tsinghua University traveled to Cornell for the third Cornell-Tsinghua Joint Workshop, April 29-30. A collaborative relationship between Cornell and the Beijing university to strengthen science and engineering education was formalized in 2004 and has resulted in several such joint workshops. Topics of presenters this year all related to sustainability and ranged from water resources to carbon sequestration.
