I am now employed as an Associate Professor at the School of Geodesy and Geomatics, WuHan University (武汉大学测绘学院) link. I obtained my Doctor degree of Engineering from Insitute of Photogrammetry and GeoInformation(IPI), Leibniz University Hannover, supervised and mentored by Prof. Christian Heipke, there I also closely cooperated with Prof. Franz Rottensteiner. I was a research intern in Vexcel Imaging GmbH, Graz, Austria, working with Dr. Michael Gruber. I obtained my Master’s degree on Geodesy and Surveying Engneering from Wuhan University, supervised by Prof. Zongqian Zhan. My research interests focus on Learning-based photogrammetry and its application, 3D reconstruction, and SLAM.
I am looking for highly self-motivated and talented Bachelor, Master and PhD students (co-supervised with Prof. Zongqian Zhan). Feel free to contact me via email If you’re interested in collaborating.
