Research Description:

Dr. Walker is an Assistant Professor in Civil Engineering at The University of Texas at El Paso. His background is in Civil Engineering and Environmental and Water Resources Engineering. Dr. Walker's research is focused on sustainable water and wastewater treatment - especially inland brackish groundwater desalination. Previous research investigated the performance of electrodialysis for treating inland Brackish Water Reverse Osmosis (BWRO) concentrate. Dr. Walker's current research focuses on improving technical, environmental, social, financial, and political sustainability of water and wastewater treatment.  Here is a list of current students and research topics:
