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. I am also interested in high-performance geocomputing techniques.
