Professional biography

I gained my first degree in Geology from Oxford Brookes University in 1979. I then worked as a Data Processing Seismologist with Geophysical Services Incorporated, based in Dhahran, Saudi Arabia. In 1983 I graduated from the University of Western Ontario, Canada with an MSc in Geology having undertaken my thesis studies on the gabbroic igneous rocks of Mont Saint-Hilaire, Quebec. I received a PhD from the University of St Andrews in 1987. My PhD studies involved a detailed field, petrologic and isotopic investigation of the contact zone of the Rum, Tertiary ultrabasic complex. I then worked as a Project Officer in the University of Cambridge, with day-to-day responsibility for running the Department of Earth Science’s three electron microprobes. In 1990 I was appointed as a Research Fellow at the Natural History Museum, London studying meteorites to investigate early solar system processes. Between 1994 and 2001 I worked in a more business-related environment, before returning to meteorite studies in my present position at the Open University. As a Research Fellow in the Department of Physical Sciences I undertake high-precision oxygen isotopic measurements of both extraterrestrial and terrestrial samples with the aim of understanding the earliest stages of solar system history.

Professional Memberships:

NASA Meteorite Working Group International Member (as from March 2015)

British and Irish Meteorite Society (since 2013)

Meteoritical Society Nomenclature Committee member (2010-2013)

Meteoritical Society Member (since 1990)

Research interests

My current research concerns the formation and early evolution of the Solar System. This work principally involves high-precision oxygen isotope analysis of meteorites and other extraterrestrial materials. To undertake these measurements I use a infrared laser-assisted fluorination system designed and built at the Open University. I am also actively involved in the characterisation and classification of new meteorites and have overall responsibility for the curation of the Open University’s extensive meteorite collection.

Impact and engagement

I have worked extensively with national media organisations, both as an expert presenter and in a technical advisory role. In front of camera television work has included BBC Star Gazing Live, BBC Sky at Night, Sky News and the Channel 4 documentary “Meteor Strike”. I have taken part in a wide range of broadcast radio interviews. I was extensively involved in helping the New Scientist Editor Roger Highfield organise their very successful meteorite competitions in 2009 and 2011.

I am in charge of the Open University’s outreach meteorite collection and both developed and maintain the associated “Open Meteorites” website. As a result of the overwhelming positive feedback we have received using real meteorite specimens to enthuse the general public about space-related science I devised the project ”Catch A Shooting Star” which received funding from STFC in 2014 and is currently being implemented in association with Manchester Museum. Current progress and further information is available on the website "Catch a Shooting Star".

For the past five years I have maintained an outreach blog aimed at a general readership entitled: “Meteorites: The Blog from the Final Frontier”.

2015: Named Collaborator, NASA Emerging Worlds Program fully funded project (14-EW14_2-0063): “Origins of Mafic Achondrites: Testing Hypothesis” (PI: David Mittlefehldt, Johnson Space Centre, Houston).

2011: Named Collaborator, NASA fully funded project: “Origins, thermal histories, and impact records of iron meteorites, chondrites, and their parent asteroids (PI: Edward Scott, Hawaii).

2008: Named Collaborator, NASA fully funded project: “Origin, thermal history, and impact record of meteorites and their parent asteroids” (PI: Edward Scott, Hawaii).

My current STFC-funded research work on hydrothermal processes on asteroids has involved extensive collaboration with Michael Zolensky (Curator, NASA, Johnson Space Centre, Houston). The Open University is widely recognised as a world leader in triple oxygen isotope analysis and as a consequence I have developed collaborative research projects with a wide range of international institutions.
