Haiying Liu

Dr. Hai-Ying Liu, senior scientist at NILU, combines ecological expertise with a passion for sustainable urban development. She holds an MSc in Environmental Protection from Inner Mongolia University, China, and a PhD in Environmental Biology from the University of Oslo, Norway.

Dr. Liu specializes in the monitoring and assessment of nature-based solutions to enhance environmental quality and public health. Her approach is both interdisciplinary and integrative, tackling the complex challenges of climate change, urban development, and public health. She is particularly focused on fostering community engagement and utilizing multi-actor participatory methods to drive environmental behaviour changes and promote health.

Dr. Liu started at NILU with a postdoctoral fellowship between 2007 and 2008, focusing on the impacts of climate change and air pollution on forest biodiversity. During this time, she also played key role in managing and coording several EU projects. Currently, her work is driven by a vision to integrate environmental quality with urban living, aiming to transform cities into resilient and healthy spaces for future generations. As a senior scientist, Dr. Liu actively leads and support coordination of EU projects and proposals. She also contributes her expertise to NILU’s grants office and sever as an evaluator for both EU and national proposals and projects.
