I am a researcher at the College of Geological Engineering and Geomatics, Chang’an University, Xi’an, China. I major in the research of monitoring and interpreting geo-hazards such as earthquakes, volcanoes, landslides, and ground subsidence using a variety of Earth Observations (EO). My main objective is to develop a geo-hazard Early Warning System (EWS) with the capacity of early-stage hazard detection and pre-warning, risk assessment of the hazard affected area and rapid responding to catastrophic events.

2015.09 – 2019.07:  PhD in Satellite geodesy and remote sensing, School of Engineering, Newcastle University, UK.

2012.07 – 2015.07:  MSc in Geodesy and Surveying Engineering, School of Geodesy and Geomatics, Wuhan University, China.

2008.09 – 2012.07:  BSc in Geographic Information System, School of Geography and Planning, Sun Yat-sen University, China.
