Timothy Ginn

Timothy Ginn is Boeing Distinguished Professor of Environmental Engineering at Washington State University's College of Engineering, with a joint appointment as Affiliate Professor in the Department of Mathematics and Statistics. He holds a PhD in Civil Engineering from Purdue University (1988), MS in Civil Engineering (1985), and BS in Classics and Environmental Sciences from University of Virginia (1982). Prior to WSU, he held positions at UC Davis (1997-2015) and Battelle National Laboratories (1989-1997).

His research focuses on reactive transport phenomena in environmental systems, with specialized expertise in: groundwater age modeling, scalar dissipation theory, multidomain diffusion, pre-asymptotic dispersion, and biogeochemical reactive transport. His work integrates advanced mathematical approaches with practical applications in contaminant transport, microbial processes, and water resources engineering.

Analysis of his 15 most recent publications reveals strong emphasis on: 1) Development of novel transport models incorporating temporal dynamics 2) Experimental and theoretical studies of contaminant behavior in porous media 3) Hydrological process quantification through tracer methods 4) Biogeochemical interactions in engineered and natural systems. Recurring themes include residence time distributions, mixing-limited reactions, and inverse problem solutions.

Scientific Awards:

• Crimson Spirit Award, WSU (2022)
• Outstanding Engineering Mid-Career Award, UC Davis (2010)
• Excellence in Reviewing, American Geophysical Union (1991, 2014)

He teaches undergraduate courses in Fluid Mechanics (CE 315), Water Resources Engineering (CE 351), and Groundwater (CE 475), and graduate courses in Inverse Problems (CE 543) and Biogeochemical Reactive Transport (CE 543). Leads research on subsurface transport phenomena through his laboratory, focusing on experimental validation of theoretical models in hydrologic systems.
