This study focuses on applying technology intelligence to discover the professional communities and social networks of biomedical engineering (BME) field in Thailand. The BME field in Thailand is at the starting stage of development; therefore, the research communities and networks for collaboration among key experts has not well established yet. This paper aims to; identify BME sub-research areas that are currently focused by BME experts in Thailand; identify the professional communities of researchers and practitioners related to BME from engineering and medical field; and identify social networks of BME engineering team in Thailand. The identification of these three aspects can support the development of potential collaboration among different groups of BME experts in Thailand in the future.
