Dr James Ian Mortimer

Profile summary

Professional biography


2007-2011: BSc (Hons) Geoscience at The University of St Andrews

2012-2016: PhD in Lunar Volatile (C, N, He, Ne, Ar) Geochemistry at The Open University


April 2016 - September 2016: Charge d'Etudes at Universite Claude Bernard Lyon 1, Lyon, France (short contract to conduct a study into the sublimation and subsequent isotopic fractionation behaviour of water ice under vacuum, in support of ESA's PROSPECT lunar exploration package)

October 2016 - March 2017: Project Officer at The Open University (short term contract to prepare and characterise two carbonaceous chondrite meteorite standards for future verification of the ESA PROSPECT package 'ProSPA' instrument)

March 2017 - May 2018: Project Officer at The Open University (fixed term contract to study the interaction of spacecraft thruster exhaust gases with the surface of Phobos and to quantify likely contamination levels of H, C, and N)  

Research interests

  • Volatiles in the Solar System, particularly light element volatiles (including H, C, N, O, noble gases etc.), and their source(s) and delivery and contributions to the volatile budgets of airless bodies and telluric atmospheres

External collaborations

  • Part of the extended ESA PROSPECT User Group (PUG) of scientists from various European countries.
