12:30 - 1:30 p.m.
Bren Hall 1414

“Beyond the Black Box:
Integrating Advanced Characterization of Microbial Processes
with Subsurface Reactive Transport Models”

Hosted by Bren Professor Arturo Keller



In this talk I will introduce the audience to the amazing world of subsurface microorganisms and present some novel approaches for incorporating new knowledge and data into reactive transport simulations. Particular focus will be given to genome-scale models of microbial cell function, and how these models are being integrated into simulations of contaminant transport and fate in groundwater systems. These will be presented in the context of the application of in situ bioremediation that aims to immobilize uranium in groundwater through microbially mediated metal reduction.


Timothy D. Scheibe joined Pacific Northwest National Laboratory (PNNL) in September 1992 and is currently a staff scientist in the Hydrology Technical Group. He received his bachelor’s degree in geological engineering from Washington State University, a master's in civil engineering from the University of Washington, and a PhD in civil engineering from Stanford University. At PNNL, he has been responsible for proposal development, project management, and technical contributions in a number of different areas of environmental research and technology development broadly related to the hydrologic sciences.

His primary research focus is on characterization and numerical simulation of natural subsurface heterogeneity, and its impacts on biogeochemically reactive transport in groundwater systems. His research projects include both computational and field experimental elements. Recently, he has worked on problems in the area of subsurface biogeochemistry, including microbial transport in groundwater, and bioremediation of metals and radionuclides. He is currently collaborating with computational scientists and applied mathematicians to simulate coupled flow, transport, and biogeochemical processes at cellular, pore, and continuum scales.


NOTE: Research colloquia are hosted by Bren faculty members and are generally high-level talks about research in a particular area of environmental science and management.
