Science knows no national borders, as Wu himself demonstrates. Though he lives with his family in Munich, he has in the past taught and done research abroad. He has been a visiting professor at Princeton University in the US, the Japan Atomic Energy Research Institute, the University of Toronto, Canada, and Stockholm University in Sweden.
科學無國界，他雖然與家人定居慕尼黑，但是經年在外講學、研究，曾任美國普林斯頓大學、日本東京原子能研究所、加拿大多倫多大學、瑞典斯德哥爾摩大學等客座教授。
