Dr. Neti Ngernpaet is a researcher in microbiology with a particular focus on freshwater microalgae, especially desmids and their ecological roles in tropical aquatic ecosystems. He is affiliated with the University of Phayao, Thailand, where his work integrates taxonomy, ecology, and environmental monitoring. His research primarily explores the diversity, distribution, and ecological significance of desmid genera such as Euastrum, with an emphasis on their application as bioindicators for water quality assessment. He has conducted extensive field surveys across Thailand, examining relationships between algal communities and physicochemical parameters including pH, dissolved oxygen, conductivity, and nutrient concentrations. In addition to algal ecology, Dr. Neti has experience in cyanobacterial studies, particularly Nostoc spp., focusing on biomass production and extracellular polymeric substances (EPS) and their potential applications in environmental and agricultural systems. His work aims to contribute to a deeper understanding of tropical freshwater biodiversity and to support sustainable water resource management through biologically based monitoring approaches. He is particularly interested in bridging classical taxonomy with modern ecological analysis to enhance the use of microalgae as sensitive indicators of environmental change.
