DESCRIPTION:The element vanadium (V) has been applied to challenges spanni
 ng Earth and Environmental Sciences.  It is a critical metal\, with indust
 ry applications in next generation batteries and as a steel alloy. It has 
 rich redox chemistry with multiple oxidation states\, prompting decades of
  oxygen fugacity (fO2) proxy development at high and low temperatures\, on
  Earth and other planets. Some organisms even employ V in place of iron to
  carry oxygen in their bloodstreams.  However\, vanadium\, in its 5+ oxida
 tion state is also highly toxic and is increasing recognised as a potentia
 lly serious environmental pollutant. The isotopic composition of vanadium 
 can be applied to investigate all of the above scenarios. The first method
  to measure V isotopes to a precise useful for Earth and environmental sci
 ence applications was developed in the Earth Science department at Oxford 
 circa 2009. In this seminar\, I will discuss how that analytical developme
 nt unfolded\, and how the applications of vanadium isotopes have evolved f
 rom initial lofty ambitions of a direct fO2 proxy in magmatic systems to c
 urrent potential breakthroughs in environmental pollutant tracing.\nSpeake
