Researchers - Theme 1

Theme 1 (Materials Scale) generates new fundamental knowledge about phosphorus capture at atomic and molecular scales using discovery-driven approaches (i.e., biological inspiration, chemical analytics). Integrated with Materials Informatics (MI), Theme 1 accelerates the development of novel capabilities to promote the facile transformation of organic and inorganic phosphorus and enable the efficient capture and recovery of phosphate.

Researchers - Theme 2

Theme 2 (Human-Technology Scale) implements materials and technologies from Theme 1 in both aqueous suspensions (e.g., surface water and wastewater) and the plant-soil-microbial system by using laboratory, greenhouse, and field-scale techniques. Theme 2 applies state-of-the-art scientific approaches including nanoscale spectroscopic characterization of phosphate speciation in soils, novel sensor development to improve tracking of phosphorus in soils, genome-wide approaches for selecting and engineering crop systems with enhanced phosphorus utilization, and development of next-generation, plant-responsive fertilizers.

Researchers - Theme 3

Theme 3 (Regional and Global Scale) identifies intervention portfolios (e.g., innovative technologies, best management practices) that enable the realization of the 25-in-25 vision and are resilient to socio-economic, policy, and environmental change, using integrated modeling at global, regional, and local scales and social network analysis. Theme 2 data about the flow and management of phosphorus as a function of space and time (e.g., through urban, aquatic, and agricultural systems) guide research prioritization in Themes 1 and 2.

Researchers - Convergence Informatics

Convergence Informatics (CI) research initiative provides data-science-driven guidance for the design of novel and effective materials, technologies, and strategies for phosphorus capture, decomposition, and modification to realize the opportunities presented by Theme integration. CI builds upon an MI-based approach in which process-structure-properties-performance relations are designed by analyzing large materials data sets with machine learning algorithms.

Researchers - TBL Sites

Specific geographical sites or Triple-Bottom-Line Scenarios that represent urban, agricultural, and aquatic systems provide technological constraints, potential impact scenarios, and connection to unique types of stakeholders in phosphorus sustainability.

Independent Evaluator

Kristi is the Assistant Director for Program Evaluation at the University Office of Evaluation and Educational Effectiveness (UOEEE), an independent unit at Arizona State University that is placed outside the purview of academic colleges and schools such that they can provide critical evaluation services from an external perspective.
