Dr. Cath is a professor of environmental engineering at the Colorado School of Mines. His main field of research is membrane and biological processes for wastewater treatment, desalination of saline and hypersaline brines, reclamation of impaired water for potable reuse, and energy from water and wastewater. Dr. Cath is a PI on many research projects focusing on the integration of membrane contactor processes in seawater and brackish water desalination, in domestic and industrial wastewater treatment (including oil & gas wastewater), and in life support systems. Additional research focus is on advanced control system for early detection of system failure, techno-economic analysis and life cycle assessment of water-energy systems, and decision support tools to select efficient and low energy treatment technologies for a broad range of water and wastewater applications. Prof. Cath is the director of the Advanced Water Technology Center (AQWATEC), Co-Director of the Colorado Center for a Sustainable WE2ST, and he holds a joint appointment at the National Renewable Energy Laboratory (NREL).
