Professor Peng is a broadly trained environmentalist with interdisciplinary expertise in land use and food sustainability, climate change, and water resources. Originally from Guangdong, she received her B.S. in Geosciences and B.A. in Philosophy from Peking University in 2013, and her Ph.D. in Environmental Engineering from Princeton University in 2019. Before joining the University of Hong Kong (HKU), she served as Chief Modeler for the Food Programme at the World Resources Institute in Washington, D.C., where she developed decision-support tools to guide carbon-neutral agriculture in Denmark and Africa.
At HKU, Professor Peng is a joint assistant professor at the Department of Geography and the Institute for Climate and Carbon Neutrality. She leads the Accounting and Policy for Land Use Sustainability (APLUS) research group, aiming to achieving food sustainability and providing solutions to mitigate the climate impacts of land use activities. She has published in high-impact journals including Nature, Nature Sustainability, Nature Geoscience, Nature Food, and Global Change Biology. Her current work involves developing carbon accounting models for forestry and agriculture to support global and national land use policy recommendations.
She is a Doris Zimmern Hong Kong University Visiting Fellow at the University of Cambridge, an editorial board member of Communications Sustainability, and an Associate Editor of Environment, Development and Sustainability.
