Hevelyn Da Silva Monteiro's PhD research aims to combine (U-Th)/He geochronology with in situ SHRIMP-SI (Sensitive High-Resolution Ion Microprobe – Stable Isotopes) d18O measurements of goethite to derive a continental paleoclimatic curve. Hevelyn's research also involves the study of the diffusion behaviour of 4He in goethites and the application of cosmogenic 3He to unravel the history of surface exposure of old landscapes.
