Researcher biography

Dr. Chang He is a postdoctoral research fellow in QAEHS. Chang completed his PhD on investigation into the sources, fate and exposure to organophosphate esters in Australian environment with Prof Jochen Mueller. His key interests at QAEHS are on the relationships between the environment and humans for a range of organic pollutants, including flame retardants, plasticizers, paraffins, etc.

AXA Fellowship

Dr Chang He has been awarded an AXA Fellowship and will investigate Understanding Human Exposure to Contaminants of Emerging Concern Through New Biomarkers.

Human biomonitoring is the gold standard for the assessment of human exposure to chemicals, but it is so far poorly understood. This project aims to investigate the biotransformation of contaminants of emerging concern, and identify their transformation products, using in silico, in vitro and in vivo strategies. This project expects to establish a systematic and accurate method of assessing human burden to chemicals using biomonitoring techniques. The outcomes of this project include the discovery of the biomarkers of emerging contaminants and the safety assessment of these emerging contaminants. This will provide significant benefits, such as a risk assessment to emerging chemicals, which will provide insights on which chemicals should be paid attention to, and if their production and usage should be banned nationally and globally. The identified biomarkers and developed analytical method will also be applied to the Australian population to assess the exposure to contaminants of emerging concern using the unique environmental and human specimen banks that has been established in QAEHS.
