Geographic Information Science, Remote Sensing, Hazards
My career goal as a researcher is to contribute to the two sub-fields of geography: GIScience and hazards and bridge the gap between these two sub-disciplines. My research objectives are to: 1) investigate the influence of spatial, temporal, and social scales of analysis on modeled outcomes, and model the variance and uncertainty resulting from change in scale of analysis and resolution; 2) explore the spatially and temporally changing surface of physical risk, social vulnerability, adaptive capacity, and resilience of communities susceptible to natural and human-made hazards; 3) enable increased participation and collaboration among public and private stakeholders and at-risk communities; and 4) help local policy makers develop a framework integrating preparedness and mitigation strategies/policies to increase a community's reslience and adaptive capacity. To fulfill my objectives, I pursue research in spatial analys and modeling (develop algorithms and tools to model the interaction between social and physical environments that contribute to socio-economic impacts resulting from hazards); visualization, web-mapping and database (develop Spatial Decision Support Systems and data repositories to provide access to data and help stakeholder participation in decision-making); remote sensing (explore spatial and temporal change in land use/cover that contribute to future hazard impacts), and education (develop learning modules following Service Learning and Game Based Learning pedagogies to increase student participation in reasearch and student retention/enrollment), among others.
My current research projects include:
- Geo-targeting at-risk communities to deploy effective crisis communication approaches
- Developing a Multi-Criteria Decision Analysis Tool to explore the relationships between perception of communities and their responses to Commercial Mobile Service and other hazard warning systems. The first project is funded by the Department of Homeland Security's Science and Technology Directorate. The second project is a component of the first project.
- Improving Economic Resilience of the U.S. Gulf Coast Communities to Coastal Hazards
Multi-scale Modeling of Risk and Loss Hot-Spots Associated with Storm Surge/Coastal Flooding.
- Project funded by the USM Lucas Endowment Award
- Determining Effective Data Sets for Risk Assessment in the Absence of High Resolution Data
