Biography

During the completion of both a Bsc (Geology) and Mres (Science) degree at the University of Portsmouth, my research focused principally on incorporating both the Pb-Pb ratios of feldspar and Ar-Ar dates of amphibole in an attempt to determine provenance of Greenland derived ice rafted debris (IRD).

Following this, I was offered an internship at the Pheasant Memorial Laboratory (PML) in Japan, whereby I (as part of a team) examined numerous aspects of the Chelyabinsk meteorite (Rb/Sr, Sm/Nd, trace elements) to better understand its origin and formation history. I have since moved on to study a PhD back at the University of Portsmouth, where I now focus primarily on the effects of impact derived shock metamorphism on mineral phases of geochronological importance (baddeleyite, zircon, etc).

I’m also an active STEMnet ambassador, focusing on engaging with both local schools and the general public in an attempt to promote planetary science and foster interest in STEM career paths within young people. 

Teaching Responsibilities

I assist with laboratory-based practical classes in the following subjects:

  • Level 4: Mineralogy and Crystallography
  • Level 4: Petrology
  • Level 5: Igneous and Metamorphic Petrology

Research

  • The effects of shock metamorphism on mineral phases and isotopic systems (principally U-Pb) within extra-terrestrial meteorite samples.
  • Dating of Martian meteorite samples to better understand the crystallisation and impact history of Mars.  
  • Development of single-shot laser ablation (SS-LA) techniques on small (5-15μm) spot sizes to better analyse both micro-baddeleyite grains and fine scale zoning in zircon.
  • Experimental shocking of solid rock samples in an attempt to recreate impact-derived pressure-temperature conditions.
