Geoinformatics for Food, Energy, and Water

My research focuses on interdisciplinary research agenda on food, energy, water, and their dependent social systems. As our society depends on sustainable supplies of food, energy and water resources embedded in diverse geographic and social contexts, innovative solutions to characterize and understand the system is critical to cope with imminent environmental and social challenges such as climate change and social inequality.

Groundwater Sustainability

As groundwater resources have been increasingly susceptible to climate variability and change in many semi-arid regions, there is a critical need to understand the challenges of sustainable water resource management and to develop coping strategies. Groundwater sustainability can be understood from a social-ecological system (SES) perspective, or viewed as a critical part of Food, Energy, Water (FEW) nexus.

AI and Big Data for FEW

I currently work on three projects related to AI and Big Data for food, energy, and water research: (1) Using GeoAI to identify hydraulic drainage structures (i.e., culverts and bridges) for terrain-based drainage modeling (water), (2) Using social media and machine learning to examine the public perception of fossil-fuel and renewable energies (energy), and (3) Using drone images and AI to identify the crop diseases (food).

Smart and Connected Rural Communities

Concerning potential widening rural-urban divide in smart society and community development, my research attempts to (1) understand smart divide by analyzing gaps in both physical and social infrastructures, and (2) smart connectivity solutions for rural health and disaster resilience. In 2020, we proposed an emerging concept - smart divide - in a paper of Annals of AAG.
