Hone-Jay Chu received Ph.D. from NCTU (2008). His research work involved artificial intelligence and optimization for water resource management. During his post-doc (2008-2011), Dr. Chu worked with Prof. YP Lin on the issue of understanding the pros and cons for the spatial environmental monitoring. They have extended the research goal to improve the performance of the land use change model. From 2011, he joined the Department of Geomatics, National Cheng Kung University as an assistant professor. His works include aiming to spatial information for cases such as groundwater, air pollution, land use/ cover change, landslide detection, historical image registration, and other GIS applications.

We are interested to generate space-time insights from remote sensing, big  data and open data for environment, and social sensing. 
Our current research covers four key themes: 1. Environmental Resilience,  2. Human Mobility, 3. Health, 4. Location Intelligence.
