Career Summary

Biography

I have recently completed my Ph.D. (Biological Sciences) and currently working as a researcher in a "Toxic Alage bioremediation" project with Dr. Thava Palanisami.

In 2017, I received the prestigious Australian Government Research Training Program (RTP) scholarship to pursue my doctoral research.

My major research areas are

  • Metagenomic analysis of microbial biofilms
  • Microplastic pollution
  • Toxic contaminant monitoring and risk assessment
  • Aquatic Microbiology and environmental health

Since 2019, I have been working as a STEM mentor with the HunterWISE group at the University of Newcastle.

The ubiquitous presence of microplastics in the food web has been established. However, the mass of microplastics exposure to humans is not defined, impeding the human health risk assessment. Our objectives were to extract the data from the available evidence on the number and mass of microplastics from various sources, to determine the uncertainties in the existing data, to set future research directions, and derive a global average rate of microplastic ingestion to assist in the development of human health risk assessments and effective management and policy options. To enable the comparison of microplastics exposure across a range of sources, data extraction and standardization was coupled with the adoption of conservative assumptions. Following the analysis of data from fifty-nine publications, an average mass for individual microplastics in the 0¿1 mm size range was calculated. Subsequently, we estimated that globally on average, humans may ingest 0.1¿5 g of microplastics weekly through various exposure pathways. This was the first attempt to transform microplastic counts into a mass value relevant to human toxicology. The determination of an ingestion rate is fundamental to assess the human health risks of microplastic ingestion. These findings will contribute to future human health risk assessment frameworks.
