Dr. Wartini Ng

Biography

Wartini Ng is a Postdoctoral Research Associate in Soil Sensing at the School of Life and Environmental Sciences, University of Sydney. She received her Bachelor of Science degree cum laude in Environmental Engineering from the University of California, Riverside, and her PhD in Soil Science from the University of Sydney. Dr. Ng's doctoral research focused on integrating novel data analytics and proximal sensing to analyze soil conditions. Her work explores the use of machine learning and deep learning methods to improve prediction accuracies of soil properties using large spectral databases. Her research interests include designing combinations of measurement and modeling approaches to solve agricultural and environmental problems. She has utilized proximal sensing technologies, mid-infrared, and near-infrared spectroscopy for the rapid acquisition of soil properties and for the potential identification of soil contamination, including petroleum hydrocarbons and microplastics. Dr. Ng is particularly interested in understanding how soil varies in space and time through digital soil mapping. She collaborates internationally with colleagues in the USA, Brazil, France, Indonesia, and Korea. Her research aligns with the Faculty of Science Research Strengths in areas such as Understanding Planet, Food Security, Healthy Ecosystems, and Climate Change.
