I am an Isotope Geochemist primarily interested in how Earth became and has remained (mostly) habitatable for the past 3.5 billion years. I primarily use uranium and vanadium isotopes as novel proxies for tracing past changes in marine oxygenation levels and nitrogen isotopes to understand past changes in biological productivity.

I trained as a chemist at the University of York and wrote my doctoral thesis in Australia at the University of Wollongong. Following a brief spell working in industry as an Environmental Consultant in Sydney, Australia, I spent my postdoctoral years in Germany at the Leibniz University Hannover.
