Dr Ann Zhang joined ITOPF in 2012. She has a BSc and an MSc in environmental engineering and a PhD in chemical engineering. Her doctoral research investigated alternative energy storage systems using nano-composites derived from carbon materials.

Since joining ITOPF, Ann has attended a number of incidents worldwide. She has been involved in various aspects of post-incident activities, including impact assessment, at sea and aerial surveillance, shoreline clean-up, water sampling and claim assessment.

Previous Experience

Prior to joining ITOPF, Ann worked as a research fellow at University of Leeds. She investigated the interactions between model cell membranes and inorganic nano-materials in aqueous environment. Through her seven years' postgraduate research experience, she has built a comprehensive understanding of the analytic techniques and the approaches to problem-solving. She also co-supervised MSc and PhD students, and collaborated with industrial and academic partners in many parts of the world.

ITOPF Working Groups

Ann is a member of the Hazardous and Noxious Substances (HNS) working group.
