- I am a University Postdoctoral Research Fellow researching the origin and evolution of life. I obtained my D.Phil. from Oxford University in 2004 studying the effects of sulfate-reducing bacteria on biomineralization. My current research focuses on morphological, chemical and isotopic tracers of primitive Archean life, using cutting edge techniques such as NanoSIMS and Transmission Electron Microscopy. I have recently authored a new introductory textbook on Archean life entitled ‘Early Life on Earth: A Practical Guide’, released in 2009.
- Key research
- My research seeks to elucidate how and when life originated on Earth and whether it could have originated on other planets such as Mars. Within this framework, I am part of a multidisciplinary team based jointly at the Centre for Microscopy, Characterisation & Analysis and the School of Earth & Environment.
- I use a variety of research tools, including field based mapping and sample collection in Australia, optical and scanning electron microscopy, state of the art computer based imaging, microbiology and high resolution geochemistry.
