Suthira Maneechai is an Associate Professor in the Department of Biology, Faculty of Science, Mahasarakham University, Thailand. She obtained her academic training in biological sciences with specialization in plant physiology and phytochemistry. Her research focuses on plant physiology, phytochemistry, and natural products, particularly the investigation of bioactive compounds in medicinal and leguminous plants such as Cajanus cajan, Tinospora baenzigeri, and members of the Loranthaceae. Her work integrates morphological and anatomical studies with advanced analytical techniques, including HPLC and LC–MS/MS, to elucidate phytochemical profiles, antioxidant activities, and plant responses to abiotic stresses, especially salinity. She has extensive experience in hydroponic cultivation systems and stress physiology, aiming to promote sustainable agriculture and the development of functional plant-based resources. She has published in international journals and actively contributes to teaching and academic development in plant science.
