Bio
Richard Xu is passionate about creating new technologies that define and transform the sustainable future of our life. His research interests include sensing technologies, electromechanical transducers, wireless sensor networks and non-intrusive energy monitoring. He holds a B.S. (Summa Cum Laude) in Mechanical Engineering from University of Michigan, Ann Arbor, and M.S. and Ph.D. in Mechanical Engineering from UC Berkeley. Currently, he is a postdoctoral researcher at BECI. Richard believes the future quality of life depends on a healthy, sustainable environment. Originally from China, he has advocated and participated into a number of clean energy campaigns in both U.S. and China. He sees himself in the future as a cultural translator, who leads and inspires collaborations between the U.S. and China in the area of environmental technologies.
