Dr. Doris WT Au, Ph.D. (The University of Hong Kong and Portsmouth University, UK), is currently Associate Professor in the Department of Biology and Chemistry, City University of Hong Kong.

The DA lab is interested in toxicology research. Her team applies omics, molecular, biochemical and cellular approaches, together with relevant whole organismal phenotypic endpoints, to identify underlying mechanisms and to predict population level consequences. Her current research is focused on the investigation of multigenerational toxicity, with special interest in studying transgenerational inheritance of skeletal deformity, reproductive and immune impairments induced by environmental contaminants and physical stresses (including endocrine disruptors, polycyclic aromatic hydrocarbons, hypoxia) using various medaka models.  The primary goals are for elucidating the underlying epigenetic/genetic mechanisms, developing novel prognostic/diagnostic epigenetic biomarkers and assessment of ecological and public health risks. She also has a keen interest in studying telomere and telomerase biology in fish and developing medaka as an alternative vertebrate model for aging research. Dr Au has over 120 peer reviewed publications and delivered over thirty invited symposia/plenary/ keynote lectures.

In 2015, Dr Au received the Brain Pool Fellowship, awarded by the prestigious Korean Federation of Science and Technology Societies, South Korea. She was also the Distinguished Lecturer in Toxicology, awarded by the Toxicology Centre, University of Saskatchewan, Canada in 2008. Dr Au is currently the co-Chair of the International Scientific Committee for the International Symposium on Toxicity Assessment (ISTA), which is a signature toxicology symposia series since 1983.  She is/was the guest editor for the journals Marine Pollution Bulletin and Environmental Science & Pollution Research, editorial board of the Ecotoxicology and Environmental Safety.
