Paul is currently undertaking a PhD focused on the biogeochemistry of palladium (Pd) contamination in soil. The project involves the toxicity and bioaccumulation of Pd to earthworm (Eisenia fetida). The aim is to understand the mechanism of Pd toxicity on earthworms that can be used for risk assessment in terrestrial environments. The study research team included Po-Hao Chen, Suzie Reichman, Ian Lam and Zhuyun Gu (University of Melbourne); Silvia Vignolini and Benjamin E. Droguet (University of Cambridge); Dannielle Green (Anglia Ruskin University); and Shamali De Silva (Environment Protection Authority Victoria).
Paul's previous work involved assessing the impact of polyethylene terephthalate (PET) glitter and novel cellulose nanocrystal (CNC) glitter on springtail (Folsomia candida), an international model species in terrestrial environment. The result showed that CNC glitter is a potential alternative to traditional PET glitter due to lower toxicity. Results were published in Chemosphere and presented in 2023 ASIATOX in Taiwan and 2024 Bioscience research showcase in University of Melbourne, Australia.
