The areas of my recent research in this field are performance assessment of radioactive waste disposal facilities, analysis of radioactive gas generation within waste disposal facilities, modeling microbiological degradation of organic waste compounds, characterization of LLW source terms space-time dependent gas transport modeling, and investigation of glass waste forms for the disposal of nuclear wastes. I am interested in developing integrated computer models for the performance assessment of waste disposal facilities, developing methodical procedure for the uncertainty analysis of performance assessment, performing integrated risk analysis of radioactive waste management, investigating factors that impact the decision of appropriate time scales for consideration of performance assessment, characterizing C-14 inventory in utility waste streams, and applying vitrification technology to LLW stabilization. Characterizing health and environmental risks from the use of energy, radiation, and other hazardous substances in the environment is one of my primary interests. This includes activities such as indoor radon risk management, comparative risk assessment of energy technologies, evaluation of externalities of nuclear power, developing analytical models for the assessment and comparison of radiological and chemical risks, and investigation of public risk perceptions of energy systems and radiation.
Some work is underway in biomedical application of radiation.
Current work includes using prompt gamma activation analysis for boron compounds measurements and physiology-based pharmacokinetic modeling of boron compounds.
