Biography
Tanya Peretyazhko is a geochemist with research interests in water-rock interactions and mechanisms of mineral formation on Mars. In particular, Dr Peretyazhko is interested in formation and alteration of clay minerals and iron oxides, adsorption and redox processes. These studies help to constrain physico-chemical parameters of past aquatic environments on Mars. She also has background in environmental chemistry and investigated fate of contaminants (mercury, technetium, silver nanoparticles) in aquatic and terrestrial systems.
