2007 to 2012: Post-Doctoral Research Associate, Open University

2005 to 2007: Researcher, Rumen Microbiology Group, AgResearch, New Zealand

2001 to 2004: PhD in Microbiology, University of Otago, New Zealand. Title of thesis: ‘Life at the Extreme Limits: Adaptation to Extreme pH and Temperature’

Research interests

I am currently a lecturer in EEE and also a UK Space Agency Aurora Fellow. My research focuses on understanding how microorganisms can live in extreme environments and their role in biogeochemical cycling. I am particularly interested in microorganisms that live in rocky environments, their diversity, and their role they play in mineral weathering.

My PhD was awarded from the University of Otago in New Zealand where I studied the physiology of microorganisms that live at high temperature and pH. From there I moved on to studying how microorganisms can survive in space. I have been involved in the ESA funded BIOPAN VI and EXPOSE missions, where we have been investigating the effect of low Earth orbit on microbial survival and bio-signatures.

In 2011, I was awarded a UKSA Aurora Fellow to understand how microorganisms live in extreme, rocky environments.  I am using laboratory based experiments and geochemical modelling to identify mineral alterations and secondary mineral formation, which could be used as bio-signatures for life on Mars.
