andrea: I am Andrea ‘Tracemaker’ Baucon. My research interests focus on palaeontology, with particular emphasis on the study of life-substrate interactions. In my research, I addressed three main questions: (1) What drives the distribution of burrows? (2) How do mass-extinctions modify burrowing behaviour? (3) Do life-substrate interactions exist beyond Earth? I tackled these questions using quantitative methods (fractal analysis, network theory, geostatistics) and analogy with modern life-substrate interactions (actuopalaeontology).
