For twenty three years, I’ve worked at Lawrence Livermore National Laboratory.
About half of this has been directly in the laboratory, while the other half has been leading individual projects and multidisciplinary programs.
From 1992 to 1994, I had a post-doc associate position, and my research interests were in sensor development, both high temperature ion conducting ceramics (such as for combustion exhaust monitors) as well as aqueous electrochemical sensors, such as for effluent monitoring for pH, heavy metal concentrations, etc.
In 1994, I got hired into a staff position at LLNL, and I moved into the area of waste stream mediation. Some of the projects were “Mediated Electrochemical Oxidation” (using an electrochemically-produced higher valent element, such as Ag(II) to oxidize organics to carbon dioxide) or “Direct Chemical Oxidation” which used peroxydisulfate to chew up organics (the peroxydisulfate was replenished electrochemically).
In 1998, I shifted my research interests and moved into looking at the functional lifetimes of materials in extreme radiation or chemical environments.
In 2001, this interest in materials and chemistry and compatibility coalesced into leading my own project, and by 2003, I was leading a small program at LLNL in this area.
Quick summary of my research interests:
Ceramic ionic conductors
Interaction of radiation with polymers
Polymer lifetime predictions
Computed Tomography of foamed polymer structures
Materials Compatibility, especially long-term
Material outgassing and headspace analysis
