    RESEARCH INTERESTS My research focuses on the experimental and modeling investigations of biogeochemistry of subsurface environment exposed to environmental perturbations. One of the research questions is to examine the capacity of argillaceous formation to sequestrate potentially toxic oxyanions, such as arsenate (HAsO4

    2-), chromate (CrO4

    2-) and antimonate (Sb(OH)6-) in nitrate-rich (NO3

    -) environment under redox-oscillating conditions. I perform batch experiments mainly using bioreactors to describe the redox-active components of the system, non-equilibrium oscillating conditions and biogeochemical kinetics. I also work on the systematic determination of physical, chemical and microbial influences on the redox potential (EH) measurements. Furthermore, I am involved in to the development of new analytical methods for indirect speciation fractionation of surface-bound oxyanions.

    RESEARCH AREAS Argillaceous formation under redox oscillating conditions, microbial role in the element cycling, predictive models of coupled equilibrium and kinetic processes, redox potential measurements.
