My Research Profile

I am a Professor of Geography at San Diego State University (i.e., California State University at San Diego). My research focuses on better envisioning, understanding, and planning of complex human-environment systems (CHES). Complexity theory, landscape ecology, geographic information science, and related domain knowledge (e.g., sociology, demography, and economics) leverage theoretical support toward my research and empirical problem-solving projects in CHES. My approach features a digital, computerized methodology, including geo-visualization and representation, space-time analysis, and micro-level modeling and simulation.

My work aims to integrate multidisciplinary (e.g., ecological, geomorphological, sociopolitical, demographic, economic), type-varying (e.g., qualitative and quantitative), and multi-scale (time, space, organizational) data and models. Recent projects have focused on 4-D (x, y, z, and time) agent-based models, modeling of human decisions, disaster-hazard (e.g., wildfire, invasive species) analysis, urban land change processes and mechanisms, reciprocal human-environment relationships under the coupled human and natural systems (CHANS) framework, environmental impact of human socioeconomics and behaviors under the telecoupling framework, and quantitative methods/metrics for landscape analysis and modeling.
