Biography

My research is in igneous petrology, volcanology and magmatism, with a focus on understanding processes of magma storage, chemical evolution and migration within the crust using both natural materials and experimental approaches. My current research interests include (i) using crystal textures to understand and quantify magma solidifcation and the physical behaviour of crystal mushes, and (ii) volatiles in volcanic processes, including the timing of fluid exsolution and the enrichment and migration of metals in volcanic settings. 

Current and recent research projects include:

  • using crystal textures combined with apatite geochemistry to interpret crystal mush behaviour in the lead-up to big eruptions (ERC Consolidator; PI)
  • using plagioclase crystal textures to understand mush processes in intermediate arc magmatic systems (NERC; PI)
  • defining speciation and structural environments for metals and volatiles complexes in silicate melts (in collaboration with Alex Iveson; Leverhulme Early Career Fellowship)
  • exploiting volatile diffusion in apatite to monitor magmatic processes and timescales (NERC; led by Dr Richard Brooker, University of Bristol)
  • developing the use of apatite as a tool to understand and quantitatively interpret the pre-eruptive evolution of volatiles in magma (NERC; PI)

We have a very active volcanology-petrology group in Durham. Currently working with me are: (i) Dr Martin Mangler, working on plagioclase-rich crystal mushes in subduction zone magmas; (ii) Dr Alex Iveson (Leverhulme Early Career Fellow), working on halogens and trace elements in evolved melts; (iii) Dr Charline Lormand, who is working on the behaviour of volatiles in apatite; and (iv) Dr Amanda Lindoo, who is working on crystal shape in plagioclase (currently based at Bristol).

Current PhD students include Madeleine Stow, who is working on transition metal stable isotope fractionation in granites (primary supervisor Julie Prytulak); Kris Sokól (St Andrews) who is working on fenite alteration around alkaline intrusions (primary supervisor Adrian Finch); Annabelle Foster, who is working on sintering textures in obsidian (primary supervisor Fabian Wadsworth); and Ceri Allgood, who is working on textures and experiments related to dyke propagation and flow (primary supervisor Ed Llewellin). MScR student Eshbal Geifman has recently completed her thesis on high-temperature plagioclase crystallisation experiments using a microscope-mounted heating stage.

I am always happy to hear from potential graduate students or post-docs interested in developing projects at Durham.


MScR projects available! 

There are currently two opportunities to join the group on a 12-month MScR (Master's by research) project:

Project 1. Exploring deep supply and mingling dynamics of mafic magma at Soufriere Hills Volcano, Montserrat (led by Dr Martin Mangler)

Project 2. Lithium enrichment and extraction from granite

Research costs associated with the projects will be met by the supervisor. University tuition fees are detailed here (Band 2). Applications are welcome at any time and there is no specific start date.

For further information or to discuss joining the group, please get in touch!
