Microorganisms are found everywhere in the global environment and support our lives. Extreme environments, which are hardly habitable for humans, can be the best for some microorganisms. Even in the low temperature, high pressure and dark environments as a deep sea, and even in the extremely high pH environment of concrete-inside, some microorganisms can inhabit in such extreme environments. My primary research interest lies in the environmental-, geo microbiology and biotechnology of chemolithotrophs, especially studying and application of metal metabolizing microbes and extremophiles.
