Research in the Bradley lab aims to shed new light on the biological and biogeochemical processes underlying the cycling of nutrients and energy that shape the Earth, including past, present, and future life and climate. Our research encompasses marine, cryospheric, and terrestrial settings, including: glacial geomicrobiology, permafrost and soil biogeochemistry, bio-energetics, the deep subsurface, and the global carbon cycle. The diverse settings we study are linked by overarching themes of life in extreme environments, global biogeochemical cycles, climate, and anthropogenic change.

​BBC Earth Podcast

"Strange creatures that eke out a life in a world so difficult and different to ours its hard to even imagine".

​James features on the BBC Earth Podcast, discussing the survival of life in the deep biosphere, extreme energy limitation, and the implications for alien life.
