Research Interest:

    To understand the fate and transport of nanoparticles in the subsurface environment. More specifically to interpret the mechanisms responsible for deposition or mobility of colloids/nanoparticles in the porous (soil) environment and at rock and mineral surfaces. Also, the studies focus on understanding the transport of contaminants such as toxic metal ions or environmental pollutants such as PCBs and PAHs (colloid-associated-contaminants).
