I am currently teaching the following classes:
    GEOG 5220 - Fundamentals of GIS
    GEOG 5221 - Spatial modeling and simulation
In the past, I have also taught classes such as GEOG 200 (World Regional Geography), GEOG 680 (Numerical Cartography), GEOG 685 (Intermediate GIS), GEOG 686 (GIS in Social Science and Business Research), GEOG 688/787 (Web-based GIS), and GEOG 983 (Special Topics in Quantitative Geography: Complexity in Spatial Analysis).

Research Interests

My research is focused on various areas of GIScience. I am particularly interested in (1) developing computational approaches to solving spatial decision problems that often have multiple, conflicting objectives, (2) visualization and cartography theory and methods that can be used to help understand complex spatial information in a problem solving context, and (3) landscape ecology and environment modeling with a focus placed on the development of spatially explicit models to understand ecological processes and their impacts on landscape.
