The funded projects include: “Studying the Impact of Intensification of Secondary Treatment in Carbon Management and Biosolids Process Optimization” ($142,000) and “Process Engineering Support for PdNA and Other Research Pilots” ($158,000).
Dr. Massoudieh’s research focuses on the modeling and analysis of complex natural and engineered environmental systems, with particular emphasis on sustainable stormwater management, reactive transport in heterogeneous media, and biogeochemical processes at sediment–water interfaces.
His work integrates physically based modeling, inverse methods, and data-driven approaches to address uncertainty, parameter identifiability, and scale effects in hydrologic and water quality systems. Key research themes include contaminant fate and transport, environmental tracers and groundwater age distributions, pollutant source identification, and performance assessment of green infrastructure and wastewater treatment processes.
Dr. Massoudieh has also made significant contributions to Bayesian inference, stochastic simulation, evolutionary computation, and model reduction techniques, as well as the development of extensible, object-oriented, and parallel computational frameworks for environmental modeling. Prior to joining Catholic University in 2008, he held research appointments at the University of California, Davis.
