📌 Short Bio (CV)

Jian Song is a Postdoctoral Researcher at the Geoinformatics Team, RIKEN AIP, advised by Prof. Naoto Yokoya.
He received his Ph.D. from the Machine Learning and Statistical Data Analysis Lab, The University of Tokyo in June 2025.

His research centers on creating and utilizing high-fidelity synthetic 3D environments to address real-world remote sensing challenges.
By combining advanced scene generation and transfer learning techniques, he aims to unlock scalable global 3D understanding for applications in urban planning, environmental monitoring, and beyond.

He is a big fan of Dota2 and Mahjong.
