Geobiology is truly a bridge of scientific fields, approaches, and timescales: geochemists, microbiologists, geologists, evolutionary biologists and many more come together to study the co-evolution of life and Earth. If you have some interest in any or all of the above, then the bi-annual Geobiology Society Conference in Banff, Canada, is absolutely the place to be. I was privileged to be invited to speak, presenting my research on the bio-energetics of subsurface life. I also spoke on a panel, interacted with friends new and old, learnt about fascinating new discoveries and ideas in geobiology, climbed and explored the Canadian Rocky Mountains, and uncovered more than half a billion years of Earth history hunting for fossils at the Burgess Shale. Thanks Kurt and all others involved for hosting my new favourite conference!
With less than two months until we set off for Greenland, via Iceland, activity in Germany and Denmark is ramping up for this summer’s Arctic fieldwork for the AirMiMic project (InterAct). We will spend July and August in East Greenland to understand how climatological and environmental changes are affecting geobiological factors on the ice, and head back to Iceland for a shorter field campaign. Our team are busy in the labs at GFZ, testing instruments, equipment, and experiments for the field. Final logistical details are being put in place, supplies are ordered, and shipping is arranged. The science team consists of Liane Benning, Chris Trivedi, Audrey Mourot, Matthias Winkel (GFZ), Alex Anesio, Eva Doting, and Laura Halback (Aarhus University), and myself. Having not stepped onto ‘the ice’ since my expedition to Antarctica in January 2018 (Montreal winter doesn’t count despite hitting temperatures similar to or even lower than what I experienced in Antarctica), I’m buzzing to get back to the high latitudes. We are grateful to InterAct, the Humboldt Foundation, the University of Aarhus, and Helmholtz/GFZ for supporting the expedition.
I am delighted to start a new appointment as Lecturer (Assistant Professor) in Environmental Science at Queen Mary University of London. Research in the lab will focus on geobiology, bioenergetics, microbiology of extreme environments (including Arctic and Antarctic habitats), deep biosphere, and environmental change. Interested students/postdocs/researchers please get in touch!
