Education and Experience

2007 - 2011: BSc with Honours in Environmental Geography at the University of Stirling, Scotland [1st Class].

2011 - 2012: Research Assistant at the Colima Exchange and Research in Volcanology, Colima, Mexico.

    This position focussed on the ongoing monitoring and analysis of Volcán de Colima. This included collection and analysis of volcanic thermal data, digitisation of seismic events, and taking field measurements of soil, water and fumarolic gases. Whilst at CIIV I was involved in the deployment and field testing of infrasound arrays, as well as testing a range of geochemical, geothermal and geodesic equipment. Click [here] to learn more about assistantships at CIIV.

2012 - 2013: MSc in Volcanology and Geological Hazards at the University of Lancaster, England [Distinction].

   My MSc project, "Examining rhyolite lava flow dynamics through multi-dimensional image analysis of the 2011 eruption of Puyehue Cordón-Caulle, Chile", involved studying active rhyolitic lava flows using novel imaging techniques, and won the Lancaster Environment Centre dissertation prize.

2013 - 2016: PhD in Experimental Volcanology at the Université de Strasbourg, France.

   I recently defended my thesis,  titled "Permeability evolution in volcanic systems", supervised by Prof. Patrick Baud and Dr. Mike Heap. The research involved suites of deformation experiments on volcanic rocks (primarily samples from Volcán de Colima), in order to assess how the physical properties of edifice rocks can impact the dynamics of a volcanic eruption. These experiments were complemented by field data and numerical modelling. The research was funded through the Initiative d'excellence [IDEX] framework.


Current Research

 Currently I am working under the DESTRESS framework [a Horizon 2020-supported project].  DESTRESS [Demonstration of soft stimulation treatments of geothermal reservoirs] seeks to  develop a comprehensive compilation of good practices for successful geothermal projects through demonstration and research. My research comprises an investigation of the potential influence of chemical stimulation on reservoir productivity and strength at the laboratory-scale, with specific focus on potential stimulation projects at Soultz-sous-Forêts [France].
