Dr. Oraphan Sungkajanttranon is an Assistant Professor in the Department of Science and Bioinnovation, Faculty of Liberal Arts and Science, Kasetsart University, Kamphaeng Saen Campus, Thailand, where she has served since 1993. She received her B.S. (1988) and M.S. (1991) in Agriculture and her Ph.D. in Forestry (2018), all from Kasetsart University. She also holds a Certificate of International Environmental Leadership from Yokohama University, Japan (2011), earned through a short-term course on sustainable living with environmental risk. In 2012 she received a Certificate of Participation from the Slovak University of Agriculture in Nitra, Slovak Republic, for an intensive course on Sustainable Agribusiness.
Her research covers plant taxonomy, anatomy, ecology and biodiversity, with a particular focus on the family Araceae and the genus Amorphophallus. Over more than two decades she has surveyed plant diversity in many of Thailand’s national parks, including Erawan, Chaleamrattanakosin, Doi Inthanon, Doi Suthep-Pui, Mae Takhrai, Khlong Wang Chao, Khlong Lan, Tham Pla-Namtok Pha Suea and Mae Surin. This work has documented how Araceae species are distributed from western to northern Thailand and how factors such as altitude shape that diversity. Her studies also cover leaf anatomy, crystals and idioblasts in Amorphophallus and Pseudodracontium, pteridophyte flora, and the phenology of arum plants under greenhouse conditions.
Beyond taxonomy, Dr. Sungkajanttranon has worked on the practical and economic uses of plants. These include the economic value of taro and wild taro, the use of wild plants by local communities, and medicinal balm made from plant oil extracts. More recently she has studied the phenology and growth of Amorphophallus muelleri for commercial konjac powder production in Mae Sot, Tak Province. She has also surveyed and documented tree species, including Fabaceae trees, in the protected areas of Kasetsart University’s Kamphaeng Saen Campus.
She is also committed to teaching and to developing teaching methods. Her work in this area includes using cooperative learning to improve achievement in General Botany, transferring techniques for preparing permanent plant tissue slides as teaching media, and evaluating the university’s Bachelor of Science program in Biological Science. Her publications appear in Scopus (ID: 57193258111), and her ORCID ID is 0000-0002-2334-7221.
