Jingjing Liang


Associate Professor, Purdue University

Founder & CSO, Science-i

Jingjing Liang is an associate professor of quantitative forest ecology at Purdue University. He has founded Science-i in 2022, and co-founded the Global Forest Biodiversity Initiative (GFBI) in 2016. Jingjing Liang has developed the first comprehensive global forest inventory database GFBi with more than 1.3 million sample plots. Jingjing Liang has been working on connecting machine learning and big data in studying fundamental questions in biodiversity and ecosystem processes, ecological and socioeconomic impacts of biological conservation. A strong advocate of open data in global forest research, Jingjing Liang has served the scientific community with data and data products, as well as high-impact research discoveries on the world’s forest resources and their conservation.
