Dr Kirsi Keskitalo

I'm an environmental geochemist with research expertise in organic carbon dynamics and isotope geochemistry in both terrestrial and marine environments. My work has largely focused on the Arctic areas trying to understand degradability of organic matter following permafrost thaw. I also research carbon storage in seagrass environments in the Maldives.
