LANL Positions

Ed has been a staff scientist since January, 1999 and is currently a Scientist 4.  He was co-team leader for the Subsurface Flow and Transport Team of the Computational Earth Sciences Group at LANL from 2008-2014 where he supervised a team of roughly a dozen Ph.D.-level scientists and technicians. He is currently the Department of Energy's CAU Lead for Yucca Flat at the NNSS on the UGTA Activity where he coordinates all scientific activities for the DOE.


Professional Societies

Ed is a member of the American Geophysical Union (AGU) and the Geological Society of America (GSA)
