My research focusses on understanding the interactions between microorganisms and their geochemical and physical environment, over timescales from days to millions of years. I study some of the most remote and extreme environments on Earth, ranging from the Arctic and Antarctica to the deep ocean. My approach combines modelling and theory development with measurements and experimentation in the field and laboratory.
I joined QMUL from the University of Southern California, where I was a Postdoctoral Fellow of the Centre for Dark Energy Biosphere Investigations and the Deep Carbon Observatory. I previously undertook undergraduate and PhD degrees at the University of Bristol. I also hold a Humboldt Fellowship at the GFZ Postdam.
