MultiTroph conference in Beijing 2024

The 2024 MultiTroph conference will be held in Beijing, probably from 18 to 24 March and will be hosted by Chao-Dong Zhu (IOZCAS). The conference will include three days of talks, some extra time for coordinating the upcoming field season in 2024 and a field trip. The event is coordinated by Qing-Song Zhou and Xiaoyu Shi. More information will follow soon.
