I am recently working as an honorary research associate in the Department of Botany at Chulalongkorn University in Bangkok. Although my current research focuses on taxonomy of Orchidaceae and Asclepiadaceae, my first research project was on bryophytes. My interest in all kinds of small plants including bryophytes developed during fourth grade in Phuket, where I was born. For my master’s degree and PhD at the University of Sydney under the Colombo Plan scholarship, I decided to study bryophytes because of their cute tiny size and the fact that no Thai researcher had previously studied them. After completing my PhD on the liverwort genus Riccia in Australia, I collaborated with Japanese Bryologists, Sinske Hattori and Naofumi Kitagawa, to identify and report 34 species of the liverwort genus Frullania in Thailand based on the specimens collected in Thailand during the expeditions of Kyoto University, Rijksherbarium, Leiden, and Aarhus University in 1957-1977. I have done research on bryophytes of mangrove forest in Chanthaburi, Krabi, Phang Nga, Ranong, Satun, and Trat provinces in Thailand and have published the list of Thai bryophytes based on the literature published from 1901 to 1979 together with Renu Sornsamran. Being the only Thai woman in Australia studying bryophytes was a great experience. I was in the same laboratory as Helen Hewson who worked on the liverwort genera Aneura and Riccardia of Borneo and had a chance to collect the plants throughout Australia.
