Dr Joel Ducoste


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.

  • Ph.D., Civil and Environmental Engineering, University of Illinois, Urbana-Champaign
  • M.Eng., Mechanical Engineering, Rensselaer Polytechnic Institute
  • B.S., Mechanical Engineering, Rensselaer Polytechnic Institute

Dr. Ducoste is a Professor in the Civil, Construction, and Environmental Engineering Department at North Carolina State University. He has over 18 years of modeling experience in a number of environmental and engineering applications. 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). Dr. Ducoste 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.

Dr Ducoste was appointed by the North Carolina House of Representative to serve on the Offshore Energy Exploration Study Committee, which is responsible for advising the General Assembly on the environmental impact of proposed off shore energy options to the State of North Carolina. He also serves as an Associate Editor for American Association of Civil Engineers (ASCE) Journal of Environmental Engineering and is a board member of the North Carolina Fulbright Association (treasurer) and the International Ultraviolet Association (IUVA). Dr Ducoste also serves on the EPA Science Advisory Board (SAB), SAB Drinking Water Committee and was a past member of the augmented Scientific and Technological Achievement Awards committee. Dr Ducoste has served on advisory committees such as the American Water Works Association (AWWA) Particulate committee, AWWA project advisor for research projects funded by AWWA, Water Environment Federation (WEF) Sewer Collection committee, and International Population Balance Model scientific and organizing committees. He is a member of AWWA, International Ultraviolet Association (IUVA), Water Environment Federation (WEF), and Association of Environmental Engineering and Science Professors (AEESP).

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.
