Ramon's background is in carbonate sedimentology with a focus on the integration of regional, outcrop, and laboratory data.

His current research interest deals with the sedimentology and geobiology of unusual hyperalkaline, lacustrine carbonate settings.

Ramon's major ambition lies in gaining insights on the ultimate paleoenvironmental significance of microbial carbonate factories by combining classical methodologies (outcrop-petrographic) data and geochemical modelling) and laboratory approaches (geomicrobiology, high-resolution biomarker analyses).

His major goal is understand the biogeochemical controls governing the multiscale petrographic heterogeneity of microbially-influenced carbonate deposits.

Research groups

Enrolled, since 2014, in a BP-University of Hull project aiming at develop a new suite of process-based insights into the origin, sedimentology and geochemistry of lacustrine carbonates in early rift tectonic settings. This project arises from an international collaboration involving the Vrije Universiteit Amsterdam and the University of Aberdeen. This project entails an innovative experimental programme focused to understand the link between solution biogeochemistry and the morphogenesis of naturally-occurring calcite precipitates.
