Research Interests

    My research focuses on developing geocomputational theory and techniques to integrate GIS and remote sensing technologies in spatial decision-making. Specific projects focus on applying spatial modeling, simulation, and optimization techniques to support land-use planning, emergency planning, and resources management.
