Associate Professor


Dr Wu is associate professor of psychology at The Hong Kong Polytechnic University. He obtained his PhD degree from University of Cambridge. His research interests are cognitive neuroscience and decision neuroscience, with a focus on the role of hormones in human social cognition and decision-making. For example, his key research questions include how testosterone influences economic decision-making such as risk choice. How does testosterone influence social preference such as altruist behavior? To address these questions, Dr. Wu combines behavioral experiments with brain imaging and hormone measurement. His research findings have been published in leading journals such as PNAS, Proceedings of Royal Society B: Biological Science, Psychoneuroendocrinology and Hormones and Behavior. Dr. Wu has been awarded research grants from National Natural Science Foundation of China and Alexander von Humboldt research foundation.
