On September 29th, Mr. Sun Yanmin (孙彦敏) formerly retired from the position in our group. He has been working on radiocarbon measurement techniques for more than 30 years in the institute, and has been a senior technician since 1998. Mr Sun joined our group in 2021, contributed to the operation and QA/QC of the AMS laboratory, and helped to setup the methodology of tree-ring and plant 14C analysis. We hope Mr Sun all the best in his new life after retirement!
