Detailed Statement of Research Interests

The overarching focus of my research is climate and society, an expanding area in global change studies, that incorporates socio-ecological interactions across multiple scales of analysis. I am particularly interested in the dynamic relationship between human development and the modification of native landscapes which are altering physical processes, as witnessed in rising global temperatures and urban heat islands (UHI), and the subsequent impacts that changing environmental systems pose on human health, well-being, and safety and security.

Climate and society serves as the point of convergence between my interests and experiences as a scholar and educator in HSGI and Geodesign. While HSGI leverages geospatial technologies to monitor and assess when, where, and to what extent a threat (i.e., heat wave, hurricane) is likely to emerge, Geodesign provides the framework to develop and advance alternative design scenarios and/or remediation strategies through discussion and negotiation with relevant stakeholder groups.

To date, my research profile includes: seven funded research projects; 14 refereed journal article publications; 8 published book chapters and reports; multiple popular press publications; and 1,133 Google Scholar citations.
