Professor Örjan Gustafsson (Prof Örjan), Member of the Royal Swedish Academy of Sciences and Professor of Stockholm University, was invited to visit GIG from April 16^th-22^nd. During the one week visit, Prof Örjan was showed around various advanced equipment of “State Key Laboratory of Geochemistry (SKLOG)” and “State Key Laboratory of Isotope Geochemistry (SKLOIG)”, gave two academic reports entitled “Large model-observation offsets in aerosol light absorption over Asia, why?” and “Cryosphere-carbon on top of the earth: organic geochemical investigation of thawing permafrost and collapsing methane hydrates in the Arctic”, and talked to colleagues and graduate students of SKLOG individually. The communications between Prof Örjan and members of SKLOG were focused on three research tracks: 1) radio carbon isotope technology and application, 2) environmental processes of black/brown carbon substances in Asian atmosphere, and 3) environmental effects of thawing permafrost and collapsing methane hydrates. Multiple collaborative plans have been consequently established.

On the 20th to 22nd, Örjan, Gan, Guangcai and Junwen went to Guilin where they visited the Longji Terraced Paddy Field (龙脊梯田）and River Li（漓江）, respectively. Against the picturesque scenery the group were able to talk extensively detail about ongoing and future collaborations. The trip finished with a farewell in Yangshou (阳朔）, and Örjan continued his trip to Beijing to visit Professors Tao Shu  (陶澍）and Zheng Mei  (郑玫）of Peking University and Professor Kang Shichang (康世昌）of Institute of Tibetan Plateau, CAS.

“This is absolutely my best trip to Asia, so far,” Örjan said. The visit is supported by “Southern Contaminants Programme (SCP)”, an International Partnership Program of CAS under the framework of Belt and Road Scientific Collaboration Initiatives.

Professor Pauzi from University of Malaya is visiting the group for one and a half month (March 5-April 20). He is a distinguished professor and scientist having been working in the areas of organic pollution, organic geochemistry for more than 30 years.  On March 23, he gave a talk on micro-plastic pollution; the talk received attention from many staffs in the lab.  His office is BiaobenLou 707. All staff and students are welcome to talk with him.
