In 2018, I finished my PhD study of machine vision for invertebrate detection on crops at the University of South Australia. In the same year, I joined The Plant Accelerator, the Adelaide node of the Australian Plant Phenomic Facility, located at the Waite campus of The University of Adelaide, as a post-doctoral researcher. Since then, I have been specialising in machine vision and machine learning for plant phenotyping and precision agriculture, especially for hyperspectral imaging-based plant phenotyping. I am currently a grant-funded researcher and my research interests include plant nutrient estimation, plant disease detection, drought and salt stress tolerance, plant growing status estimation, invertebrate pest detection, machine learning and deep learning, optical sensing system design, bio-inspired machine vision system, bird vision, insect vision, high-dimensional colour space,  3D model reconstruction and object recognition.
