Senior Lecturer in Earth Sciences, Cardiff University

My research centres around finding linkages between biogeochemical cycles and the environment, with specific aims being to elucidate how changing Earth chemistry promoted the evolution of life and how that life in turn influences atmospheric and oceanic chemistry.

This research is subdivided into: 1) Microbe-metal interactions related to the cycling of Cu, Fe, As and Si through geological time, with specific aims to develop them as biomarkers for the reconstruction of Earth history. 2) Nutrient cycles of C, S, Fe linked to Earth’s oxygenation history. 3) Arsenic and phosphorus cycling in modern and ancient systems, with a goal to unravel the impact of arsenic on biological phosphate availability.
