“If the nineteenth century taught us that the present explains the past, the twenty-first century is teaching us that the past may be our most reliable guide to the future.”




About
A field sedimentologist turned quantitative geoscientist, I work where sedimentology, palaeoclimate, data science and Earth-system analysis meet.
What drives it is a simple observation: decisions made within a single lifetime can shape environments for thousands of years. Sediment archives extend our view of floods, coasts and pollution far beyond the few decades of instrumental records, and sound planning needs that longer view.
