Short Bio

CHEN Hongruixuan is currently a Ph.D student at Machine Learning and Statistical Data Analysis Lab, The University of Tokyo, advised by Prof. Naoto Yokoya. He was also an academic visitor of Photogrammetry and Remote Sensing Group, ETH Zurich and an intern of The United Nations Satellite Center (UNOSAT). His current research is motivated by how to better monitor, describe and understand changes in our planet's surface by studying machine learning and computer vision approaches, thereby contributing to urban planning, resource management, environmental protection, and sustainable development.
