In order to summarize the recent progress and thank all alumni and group members for their contributions, and enhance the connection between graduate students and current students in the group, we organized “Global meeting of Chen-Jiang’s Group” with the participation of past and current students on September 4, 2021. Alumni in China, Netherlands, Switzerland, US and the current group members attended the meeting. In the meeting, we recalled the past and looked forward to the future. Graduated students shared their work experience in academia and industry. At last, Prof. Chen summarized the work of our group in recent years and proposed the directions for future efforts.
