In addition to these field-scale efforts he has also been involved with conducting and interpreting numerous laboratory-scale tracer and contaminant transport experiments in which solute and colloid transport were studied in natural fractures, artificial fractures, packed columns (porous media), or intact pieces of rock (diffusion studies). Batch sorption and desorption experiments have often been conducted in parallel with column experiments to assess the ability to predict reactive transport under flowing conditions from batch measurements.
Most recently, Paul has taken a position with the Yucca Mountain Program as lead technical science advisor to the testing program. In this role, he will help guide research directions and coordinate testing with the PIs, the test coordination office and the Lead Lab. Amidst this important work task, he also manages to maintain involvement with research projects in contaminant flow and transport.
