Current researches are in the field of geochemistry of sandstone; sedimentology: sequence stratigraphy and high resolution sequence stratigraphy; basin analysis; mineral composition and diagenesis of sandstone and their influence on reservoir characterization; facies analysis and depositional environment determination; isotopes and radiometric dating of clay minerals and glaucony; field geology and lithostratigraphy; and sedimentology of alluvial fans and desert landscape.
