What I do

I teach and research in the field of Geographic Information Science.

Specialization(s)

Volunteered Geographic Information (VGI), Spatial Analysis, High-Performance Geo-computing

Professional Biography

I obtained my Ph.D. in GIScience from the University of Wisconsin-Madison in 2018. During my Ph.D. study, I also obtained a M.S. in Computer Sciences in 2016. My current research is focused on the theory and application of volunteered geographic information (VGI) and computing technologies to support spatial big data analytics.

Research

My research falls in geospatial big data analytics. I am particularly interested in VGI and its applications. VGI has been an important source of geospatial big data. However, it suffers from certain data quality issues in analysis (e.g., spatial bias). My research focuses on mitigating spatial bias in VGI (and other non-traditional data) to improve the quality of inferences made from them. In addition, geospatial big data (e.g., VGI) is often massive, it is urgent to address the computational challenges facing geospatial big data analysis. A side-line of my research focuses on developing algorithmic optimizations and utilizing cutting-edge computing technologies (e.g., high-performance computing) to support geospatial big data analytics.
