I am a postdoctoral researcher funded by the Carlsberg Foundation (Carlsberg Foundation Internationalisation Fellowship) with a PhD in siliciclastic sedimentology and stratigraphy based on fieldwork in High-Arctic Svalbard. As a sedimentologist, my multidisciplinary research spans most of sedimentary geology, with a firm focus on (but not limited to) small-scale depositional processes, large-scale basin dynamics, and global-scale climate evolution. In particular, I am interested in how coastal landscapes and geomorphology respond to climate change in time and space, in order to face some of the imminent global challenges of the currently warming world.
