Research Interests


I’m a biogeochemist interested in the interactions between microbes and minerals at terrestrial environments and how these processes influence biogeochemical processes, especially sulfur. I  am specifically  interested in applying  light  (O, S) and heavy (Fe) stable  isotopes to biogeochemical processes (e.g. metal sulfide oxidation, Fe oxidation/reduction).

My research addresses microbe-mineral interactions in extreme environments (hyper saline/alkaline, acid mine environments) , microbial geochemistry of ultramafic rocks and extends to extraterrestrial research.

  • Biogeochemical sulfur cycling in extreme environments and its impacts on the oxygen isotope composition of sulfur species.
  • Biogeochemistry of Fe oxidation/reduction and its impacts on Fe isotope composition of Fe-oxides
  • Relationship between sulfur and other geochemical cycles, i.e. metals.
  • Geomicrobiology of hyper saline/alkaline lakes and biomineralization development in these environments.
  • Biogeochemistry of ultramafic rocks of NAF Zone (Adapazari-Sapanca area)and how microbes thrive on these rocks.
