Jingjing Liang Prof. Jingjing Liang

Jingjing Liang, an Associate Professor of Quantitative Forest Ecology, Department of Forestry and Natural Resources, Purdue University. He serves on the Steering Committee, Purdue Institute of Physical Artificial Intelligence (IPAI); and on the Leadership Team, Purdue Institute for a Sustainable Future (ISF).

Dr. Liang heads the Purdue Forest Advanced Computing and Artificial Intelligence (FACAI) Laboratory. At the heart of Dr. Liang's research lies a profound fascination with global biodiversity patterns and their complex interplay with environmental and anthropogenic factors. To tackle the pressing challenges in this domain, he employs cutting-edge tools like machine learning and big data analysis. He firmly believes that the future of the field hinges on robust international collaborations and harnessing the power of artificial intelligence to generate high-impact research outcomes.

Dr. Liang is a trailblazer in the realm of international research collaboration and forest science. As the founder and Chief Science Officer of Science-i, he has pioneered the development of a transparent and FAIR (Findable, Accessible, Interoperable, and Reusable) web platform, redefining the way global researchers collaborate and share knowledge. He is keen on contributing to capacity-building efforts for the Global South, as evidenced by his recent collaboration with the FAO. This experience has underscored the importance of knowledge sharing and empowerment in underserved regions.

Outside the realm of academia, Dr. Liang is an avid runner and cyclist, drawing solace and inspiration amidst the trees and nature. In this environment, Dr. Liang thrives, driven by a passion for exploration, discovery, and collaboration that defines his remarkable career in forest science and research.
