Chi Zhang
Project Title: Assessment and mitigation of micro- and nanoplastics in the dairy foods
Biography: Chi is a PhD candidate working on micro- and nanoplastics (MNPs) in food systems, with a particular focus on dairy products and food packaging. His research investigates how plastic particles enter food during processing, storage, and packaging, and how they can be accurately detected and reduced. This work sits within the bigger global challenge of plastic pollution, food safety, and sustainable packaging systems. As concerns grow around MNPs, human exposure, and environmental contamination, understanding how plastics interact with food is increasingly important.
Chi combines laboratory analysis with advanced detection techniques, including Raman spectroscopy, novel organic matter removal method, and microscopic imaging, to improve the identification and quantification of MNPs in complex food matrices. He is also interested in integrating data-driven approaches and machine learning tools to enhance detection efficiency and support circular economy strategies.
Through his research, Chi aims to contribute to safer food systems and more sustainable packaging solutions. Outside of research, he enjoys cross-disciplinary collaboration and is always keen to explore new methods that bridge environmental science, food safety, and materials science.
