​​​Job Description

Instrument Scientist, High Resolution Powder Diffractometer (HRPD).


 

Biography

My training and early career were based on planetary geology, with a focus on the properties of icy objects in the outer solar system; my first publication, on the astrobiological potential of Saturn's moon Titan was published shortly after graduating in 2000. Subsequently, I went on to study the properties of icy materials using Density Functional Theory calculations and, from 2003, using neutron diffraction. The combination of experimental and computational work formed the basis for two successful research fellowships, awarded by STFC and held in the Department of Earth Sciences at University College London. In 2013, I took up an appointment as a Lecturer jointly between UCL Earth Sciences and Birkbeck Department of Earth and Planetary Sciences. In this role, I taught introductory and advanced modules in Planetary Science and co-authored an undergraduate text-book, “Planetary Geology: An Introduction" with Professor Claudio Vita-Finzi.

Following a 6-month secondment in 2015, I joined the ISIS Crystallography Group in January 2016, as an Instrument Scientist on HRPD.


 

Research Interests

  • Phase behaviour and thermoelastic properties of 'rock-forming' minerals in icy planetary bodies. Examples include water ice, hydrates of ammonia, methane, methanol, sulfuric acid, and various sulfates. Material property data in support of planetary geology and geophysical modelling.
  • Unusual thermoelastic properties in organic and inorganic crystals, including negative thermal expansion and negative compressibility.
  • Powder and single crystal diffraction techniques on both X-ray and neutron sources.
  • Data collection under extreme conditions of low temperature and high pressure.


Grants

  • PPARC Fellowship PPA/P/S/2003/00247 (PI). “Experimental and computational studies of planetary ices".
  • STFC Advanced Fellowship PP/E006515/1 (PI). “Experimental and computational studies of planetary ices and their role in the thermal evolution of icy moons".
  • PPARC standard grant PP/C501992/1 (Co-I). “The properties of planetary forming materials and the evolution of the icy moons“.
  • STFC standard grant ST/G003637/1 (Co-I). “Laplace/Tandem bridging grant".
  • STFC standard grant ST/K000934/1 (Co-I). “Structure and dynamics of small planets and moons".


Projects

  • Upgrade to the High Resolution Powder Diffractometer, HRPD. A variety of medium to large concepts are in development to make improvements to the performance and environment of this flagship ISIS instrument.
  • In situ Raman spectroscopy combined with neutron powder / single-crystal diffraction. Affording the possibility to access dynamical information and local structure at the same time as measuring the long-range structure via diffraction, this project is currently integrating our existing portable-Raman capabilities to low- and high-T sample centre sticks. A joint studentship between ISIS, Diamond and the University of Exeter will complement and extend these efforts from late 2018.
  • Optimisation of high-pressure gas cells for high-resolution neutron powder diffraction. Current high-pressure gas cells have a wall thickness that precludes measurement of backscattering data on HRPD for all but the most simple and high-symmetry materials (even then with very long counting times). In order to collect the highest-resolution data at high pressure, a new cell with thinned segments (approximately half the thickness of the current cells) where the beam enters and exits the cell is under development.
  • In situ thermometry for highly accurate and precise thermal expansion measurements.​ A variety of tests have revealed the importance of embedding thermometry inside a powder sample during variable-temperature studies in order to be certain that derivatives (thermal expansion) are determined accurately so that interpretations are meaningful. A very simple in situ sensor for our standard slab cans is in development.
