Gregory V. Lowry, Ph.D.Dr. Lowry's research group investigates the fundamental physical and chemical processes affecting the mobility and fate of nanomaterials in the environment in order to promote the sustainable development and use of nanomaterials. Current projects include development and evaluation of novel surface coatings to enhance the transport of nanoscale zerovalent iron (NZVI) and metal-oxide nanoparticles in the subsurface, assessing the effect of NZVI treatment on the DNAPL mass and contaminant mass emission from the source zone, measuring the degradation rate and products formed during TCE DNAPL degradation by NZVI under groundwater conditions, understanding the fate of nanoparticles and their coatings in the environment, assessing microbial-nanoiron interactions in groundwater aquifers, and evaluating the potential neurotoxicity of metal-oxide nanoparticles.
