^***Limi Mao received degrees from Lanzhou University in Gansu, China (BA in geology), Tongji University in Shanghai, China (MA in palynology) and Osaka City University in Japan (PhD in biogeoscience). He is currently based at Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, as a Cenozoic palynologist in Department of Palaeobotany and Palynology. He was awarded a full professorship in 2017 and his research interests mainly focus on pollen morphology for fossil taxa and extant plants in China, Quaternary palynology, and mangrove vegetation history and its past biogeography. He is one of the key contributors of the book Atlas of Quaternary Pollen and Spores in China (both Chinese and English edition).
