RESEARCH FOCUS:

Microbially-mediated carbon cycle at the biosphere-lithosphere interface, focusing on the microbe-(carbonate) mineral interactions. Geomicrobiology of benthic microbial communities, carbonate sedimentology, paleontology and paleoecology; including studies in both fossil and modern ecosystems; in open-marine, hypersaline, freshwater and terrestrial environments. Microscopy techniques (ESEM, Cryo-scanning).
