Dan Hikuroa is a Post-Doctoral Research Fellow at the University of Auckland whose interests range broadly within the sedimentology and paleontology spectrum. He has worked in Antarctica on Jurassic sequences and faunas and is currently working on Cretaceous climate-ocean interaction in the ‘greenhouse’ and paleonviromental analysis of some Pleistocene sequences, both of which are in New Zealand. A new focus is the quantification of ‘environmental collapse’ following ‘mega-eruptions’.
