Joel Ducoste

Professor and Interim Associate Dean for Faculty Advancement

Dr. Ducoste is a Professor in the Civil, Construction, and Environmental Engineering Department at North Carolina State University. He has over 25 years of modeling experience in a number of environmental and engineering applications. He is a Board Certified Environmental Engineering member of the American Academy of Environmental Engineers and Scientists (AAEES).

Dr. Ducoste is a recognized expert in modeling water and wastewater treatment processes using Computational Fluid Dynamics (CFD).  His current research interests include physico-chemical processes in water treatment, computational fluid dynamics modeling, water/wastewater process optimization, wastewater sewer collection system sustainability, plant biosystems engineering, and solid waste process modeling.  Dr. Ducoste currently serves on the U.S. Environmental Protection Agency (USEPA) Board of Scientific Counselors (BOSC) Safe and Sustainable Water Resources subcommittee, elected board member of Association of Environmental Engineering and Science Professor (AEESP) (serves as President-elect), and board member of the North Carolina Fulbright Association.  Dr. Ducoste is a member of AWWA, WEF, AEESP, and AAEES.

Before his appointment at the university, Dr. Ducoste was a senior process engineer at CH2M HILL’s Water Business Group. He continues to participate as a senior consultant with nationally and internationally recognized firms in water and wastewater projects related to the application of CFD for analyzing designs and troubleshooting treatment problems. Dr. Ducoste also has experience in the design and construction of manufacturing processes for Fortune 100 companies.

Research Description

Dr. Ducoste is interested in the operation, design, and optimization of drinking water and wastewater treatment processes. He achieves these goals by incorporating novel experimental techniques and validated numerical models in the analysis of unit processes. He has research experience in the operation and design of chemical mixing, flocculation, sedimentation, and chemical and UV disinfection processes in drinking water treatment. Dr. Ducoste is an expert in modeling water and wastewater treatment process fluid mechanics using Computational Fluid Dynamics (CFD). He has developed CFD models for analysis of chemical and UV disinfection reactors, rapid mix chambers, flocculation basins, filtration systems, wastewater activated sludge systems, waste stabilization ponds, secondary clarifiers, and food waste systems. Dr Ducoste is also interested in modeling cellular regulatory and metabolic pathways and interfacing product formation to produce bioreactor models using CFD.
