Biography

Welcome to my website! I am currently a doctoral student in the Earth System Modelling group at the Technical University of Munich, where I am supervised by Prof. Dr. Niklas Boers. Previously, I was a research assistant at the Open Geographic Modeling and Simulation (OpenGMS) group at Nanjing Normal University, where I worked under the supervision of Prof. Dr. Min Chen.

My research is driven by my passion for merging geospatial technologies🛰️, such as geoinformatics and remote sensing, with advanced data-driven approaches such as machine learning and deep learning🤖. I'm also interested in assessing the developed models beyond their accuracy, including generalisation, explainability, interpretability, and reproducibility. My overall goal is to use these interdisciplinary methodologies to explore and deepen our understanding of the interactions between human and Earth systems, contributing to their sustainability in the Anthropocene era🌍. My academic journey can be summarised in two main areas of focus: (1) examining sustainable urban environments at various scales, encompassing infrastructure and landscapes, in response to climate change, and (2) investigating the interactions between (human-influenced) forest ecosystems and climate impacts.

Please feel free to explore this website where you can find my Full CV, the latest news about my work💻, a list of my publications📑, as well as datasets and codes📀 that I have made available to the academic community.

Simultaneous extraction of spatial and attributional building information across large-scale urban landscapes from high-resolution satellite imagery
To conduct a thorough examination of building infrastructure and develop a deeper understanding of human-urban dynamics, this study introduced a multi-task network, MT-BR, to extract unified building information. This study proposed a method for selecting representative samples for robust network training that considers both their location and the features of the urban environment they represent, so that they can be used effectively across large urban landscapes.

Vectorized dataset of roadside noise barriers in China using street view imagery
Roadside noise barriers (RNBs) are important urban infrastructures to ensure a city is liveable. This study provides the first reliable and nationwide vectorized RNB dataset with street view imagery in China. The generated RNB dataset is evaluated in terms of two aspects, i.e., the detection accuracy and the completeness and positional accuracy. The method is based on a developed geospatial artificial intelligence framework.
