Research areas

My research primarily focuses on understanding how climate, oceans and life have co-evolved during the past 500 million years. I am interested how mass extinction events and changing biogeochemical processes have shaped the surface of our planet through time. To address these questions, I develop novel elemental and isotopic analyses and apply them to fossil, sedimentary and evaporitic records. At the heart of my work lies the boron isotope technique, which I use to: 1) reconstruct past changes in ocean pH and atmospheric CO₂ levels, 2) reconstruct the secular changes in boron isotope composition of seawater and study the global boron cycle, 3) explore biomineralisation mechanisms of marine calcifying organisms, with a particular interest in brachiopods and coral reefs.

I hold a PhD in Marine Biogeochemistry (2015-2018) from GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany (Marie-Sklodowska Curie fellowship in BASE-LiNE Earth ITN). Prior to joining St Andrews I was a Postdoctoral Researcher (2018-2020) at the GFZ German Centre for Geosciences - Helmholtz Centre Potsdam, Germany (funded by the German Research Foundation and ICDP/IODP Priority Programme).
