Tim BartholomewNiles GuoYang Liu
Ph.D Student, Civil and Environmental EngineeringPh.D Student, Engineering and Public PolicyPh.D Student, Engineering and Public Policy
Research Area: Tim’s research addresses water management challenges in the energy sector. He is particularly focused on treating and managing high salinity brines (2-10 times saltier than seawater). He uses process and network level optimization models to identify treatment technologies and management strategies that are cost effective and energy efficient.Research Area: Niles’ research aims to combine expert elicitation with a concurrent engineering approach, to assist experts and decision-makers in designing and understanding complex infrastructure systems in the water-energy nexus. He is currently focusing on evaluating the effectiveness of the approach on a case study focusing on shale gas wastewater management.Research Area: Yang works on the intersection of water and energy networks. He uses optimization techniques to model and evaluate the demand response capacity in drinking water supply and wastewater treatment systems.
Amanda QuaySneha Shanbhag
Ph.D Student, Engineering and Public PolicyPh.D Student, Civil and Environmental Engineering
Research Area: Quay’s research seeks to incorporate satellite data into environmental policy analysis of the food-energy-water nexus. Her current project focuses on estimating crop switching behavior in response to salinity changes in California’s Central Valley.Research Area: Sneha’s research highlights the use of electrochemically functional insertion or phase change materials for desalination of brackish water and for selective ion removal. These materials have been widely demonstrated in the sensor and battery fields, where their high ion adsorption capacity confers unique materials advantages over surface adsorption systems. These same high capacity properties paired with selectivity to specific ions, is advantageous in conferring low material costs, long charge-discharge cycle times, and relevance of these systems in treating low to medium salinity waters.
