Jingjing Liang

Jingjing Liang, an Associate Professor at Purdue University, heads the Purdue Forest Advanced Computing and Artificial Intelligence (FACAI) Laboratory. 

His research employs AI tools and extensive tree survey data to address key questions in global forest ecology. He led an international team in creating the first global forest inventory database GFBi, featuring over 2 million sample plots worldwide. Dr. Liang’s work revealed the Earth’s tree species count and a positive link between species diversity and forest productivity. A proponent of open science, he established the Science-i platform, aiding numerous under-represented scientists globally in impactful research endeavors.
