About William

I am a hydrogeologist with broad interests including developing nanoparticles as tracers of flow and transport in porous media, Isotope and tracer hydrogeology, groundwater recharge, groundwater/surface water interactions, flow and transport in fractured media and hydrogeophysics. My work has been at the lab, field and regional scales. I have worked in Colorado, Tennessee, Australia and Libya.
