My research on glacial sedimentary environments focuses on ice-marginal settings, especially in the understanding of the relationships between subglacial till genesis and glacier dynamics. This includes the development of a genetically framed classification scheme for tills and glacitectonites, which has reconciled process data with geological criteria and has elucidated the concept of a temporal and spatial mosaic of till formation. I have further linked subglacial process-form relationships to models of landform development at modern glacier margins through a combined macro- and micro-scale approach to glacial sedimentology.
