Recent Projects
1.NSF CAREER (#2339174): A Cyberinfrastructure Enabled Hybrid Spatial Decision Support System for Improving Coastal Resilience to Flood Risks (Dr. Zhang as Sole PI, $568,302)
This CAREER project builds a Hybrid Spatial Decision Support System that integrates scalable geospatial data and visualization tools into a cyberinfrastructure-enabled framework to support decision-making in flood management. This project also establishes a scientific roadmap to advance disaster decision science using advanced cyberinfrastructure, geospatial artificial intelligence, and education activities to educate communities to better prepare for flood hazards. In the Hybrid Spatial Decision Support System, a high-performance cyberinfrastructure-based interface accelerates reading and visualizing disaster-related Network Common Data Form (NetCDF) data. Another innovation is to combine the data-driven approach with expert-driven decision analysis to enable a more accurate, comprehensive, and transparent flood risk assessment that bridges the gap between the digital world and human perception of risk. Community engagement activities and use-inspired research are used to evaluate the level of trust and transparency of using geospatial artificial intelligence and decision-making models in flood risk prediction. Finally, the project integrates research outcomes into educational curricula and activities to engage students and researchers in high-performance computational thinking for disaster management research.
2. NSF CyberTraining (#2321069): Implementation: Small: Broadening Adoption of Cyberinfrastructure and Research Workforce Development for Disaster Management (Dr. Zhang as PI, $454,847)
Disasters are prominent global issues which simultaneously pose threats to multiple countries or regions. Disaster management is gradually empowered by increasing geospatial big data awareness and growing computing capabilities to produce spatial vulnerability and situational understanding for supporting timely decisions. This project will establish an international CyberTraining for Disaster Management (CTDM) network in which disaster research communities can broaden their cyberinfrastructure (CI) and geospatial skills by participating in the proposed training activities. The project will establish a CI-enabled geospatial disaster science network among academic institutions, governmental agencies, hazards research centers, industry, and educational organizations to leverage the expertise of pertinent communities in developing training materials for preparing the next-generation workforce. A novel training curriculum is developed to consist of various training modalities such as summer schools, workshop sessions, and online webinars, which utilize CI and scalable geospatial analytics for effective disaster management practice.

3. NSF Convergence Accelerator Track E (#2137684): Combining High-Resolution Climate Simulations with Ocean Biogeochemistry, Fisheries and Decision-Making Models to Improve Sustainable Fisheries (Dr. Zhang as PI, $750,000)
Fish and shellfish populations are a vital source of protein for many of the world’s people, and several of the largest are found along the eastern boundaries of the Pacific and Atlantic Oceans, where cold, deep water moves towards the surface, bringing nutrients that support both production by plants (phytoplankton) and the fish populations that feed on them. This project aims to use these advancements to improve forecasts of the fisheries potential of the California Current Ecosystem and improve decision making by managers and other stakeholders. The project will couple the output from such a high-resolution model simulation with the Marine Biogeochemistry Library and Fisheries Size and Functional Type models, thus incorporating physics, chemistry and biology with climate variability. The results will be integrated with a prototype, web-based decision support system, that uses mathematical decision analysis capabilities, to assist fisheries managers to model the complex, climate-related decision problems on which fisheries production depends. This is vital to ensure that the region can continue to support a sustainable fishery in the long term and the communities that depend on fishing for a living.

4. NASA Earth Science Equity and Environmental Justice ROSES Project (Dr. Zhang as Institutional PI, $149, 163)
Climate change is causing extreme heat in American cities. Previous heat exposure assessments and predictions are from a top-down policy perspective, neglecting the viewpoints of different stakeholders, especially vulnerable populations. The City of Oklahoma City (OKC), OK has recently focused on urban heat mitigation by a series of sustainable plans and actions due to the increasing frequency and intensity of extreme heat events. There is an urgent need in OKC to gain a comprehensive picture of the urban areas and populations vulnerable to heat, as well as preferences and recommended decisions from different stakeholders, to conduct sustainable and equitable planning. The objective of this project is to develop an innovative Heat Exposure Index (HEI) based on NASA data and a human-environmental energy budget model; a Heat Vulnerability Index (HVI) by integrating multi-dimensions of heat vulnerable indicators, as well as a spatial decision support system to promote heat-related policymaking processes among different stakeholders, especiallyvulnerable populations.In July 2023, we have organized a community workshop.

7. A Hybrid Decision Support System for Driving Resiliency in Texas Coastal Communities funded by NOAA Sea Grant (Dr. Zhang as Co-PI, $299, 995)
This research seeks to augment current flood management practices in Texas coastal communities using citizen science, artificial intelligence (AI), and decision science, and cyberinfrastructure. In this project, we use citizen science and machine learning to compare pre-flood and post-flood photos of the same traffic “STOP” sign location to estimate the depth of floodwater at street level. The traffic “STOP” signs are used as benchmarks since their shapes and sizes are standardized anywhere in the country. Generated data will be further incorporated in a CyberGIS-enabled spatial decision support tool for residents and first responders to improve the quality and timeliness of decision-making in the event of a flood. The team has developed BluPix application.
