Geographic Information Science, Remote Sensing, Hazards
My career goal as an academician and a researcher is to contribute to the fields of GIScience and hazards by bridging the gap between these two sub-disciplines of geography. My research covers the following inter-related topics: (1) GIScience - uncertainty and accuracy assessment, multi-scale and spatio-temporal modeling, big-data (geo-privacy, visualization, data mining and Internet-GIS applications); (2) remote sensing - change detection, feature extraction; (3) hazards - physical risk/vulnerability/financial loss estimation, evacuation modeling, and community resilience. My pedagogical research focuses on Service Learning and Game Based Learning to increase students’ learning outcomes and their experience in research and practice.
My current research projects, which are funded by the Department of Homeland Security’s Science and Technology Directorate and the National Science Foundation’s Engineering Program, include:
- Explore through a functional relationship the impact of spatial scale of analysis on financial loss estimation due to storm-surge impact on residential structures.
- Optimize evacuation route and evacuation time for a hazard (e.g. within a stadium) by using network analysis, affordance theory, cellular-automata.
- Determining Effective Data Sets for Crisis Mapping Based on their Spatial and Temporal Resolutions.
- Assessing the issue of geo-privacy from users’ perspective in the era of Social Media.
- Exploring the impact of users’ knowledge of geo-privacy on accuracy of data available from social media and other big-data sets obtained through crowd sourcing.
- Explore the role of citizens on the success and failure of e-government sites.
- Develop a Multi-Criteria Decision Analysis Tool based on significant factors that influence people’s response to Wireless Emergency Alert system and other warning systems. The tool will help geo-target at-risk communities requiring effective risk communication approaches and platforms.
- Determine significant physical, political, social factors that influence the economic resilience of the U.S. Gulf Coast Communities to Coastal Hazards. Determine the impact of spatial scale of analysis on estimation of economic resilience and its spatio-temporal variability.
- Develop Game Based tools to increase student participation in research, and community awareness of hazard impacts.
- Develop online Spatial Decision Support Systems to increase participation of stakeholders to address hazard impacts and mitigation issues.
