Professional biography

More information is available on my personal website: www.nataliestarkey.com

I'm a Post Doctoral Research Associate in Planetary and Space Sciences at the Open University funded by the Science and Technology Facilities Council (STFC). I work on analysing small cometary and meteoritic samples with a NanoSIMS, which is a type of mass spectrometer that measures different elements and isotopes. I am studying extraterrestrial samples in order to understand the distribution of silicate and organic reservoirs in the early Solar System. Isotopes can trace the processes acting on these reservoirs over large and small scales in the early Solar System, helping to piece together the history of how the planets and other Solar System bodies formed. Comets also contain organic material which can help us to understand how the initial seeds for life may have been delivered to Earth.

I began my science career with a Geology degree at Durham University followed by a Geochemistry PhD at Edinburgh University. I currently supervise two PhD students and, in addition to my own research, I am Deputy Head of the NanoSIMS laboratory. This aspect of my job involves analysing a range of geological samples such as martian meteorites, Lunar Apollo samples and terrestrial samples, measuring a whole suite of different elements and isotopes.

I am a STEMNET ambassador which involves speaking to school children about my science in order to enthuse them into a science career.

Research interests

Current Research

My current research focusses on a wide range of space materials from samples of comets and meteorites to interplanetary dust particles. I focus on the mineralogical, chemical and isotopic characteristics of these samples using instruments such as FIB-SEM, FEG-SEM and NanoSIMS. I am particularly interested in investigating how these materials can help us to understand the origin and formation of the early Solar System.

I am Deputy Head of the NanoSIMS laboratory in PSS which involves training users for internal and external projects as well as continuing developmental work for new isotope systems.

Main interests:
NanoSIMS, Cometary samples returned from STARDUST mission to comet Wild2, Interplanetary Dust Particles collected in the Earth's stratosphere, Meteorites, Mantle geochemistry, Noble gases in the Earth's mantle, Large Igneous Provinces, Melt inclusions.
 
I supervise 2 PhD students:
Jean-David Bodenan (Open University/NHM) PhD title is: Characterisation of oxygen isotopic reservoirs in the early Solar System
Epifanio Vaccarro (Open University/NHM): Physical and Chemical Properties of Matrix in Primitive Chondrites.
