I have been a member of the Society since the early 90's as a student and I'm the current Treasurer of the GSNZ, based at NIWA Wellington. My current research is primarily focused on post-glacial marine dispersal and depositional events on continental shelves, slopes and basins. Collaborative research within active research programmes includes the application of detailed analysis of sediment cores, event chronology, and paleoseismology, all of which use high resolution seismic, multibeam bathymetry and backscatter, and sedimentary physical properties. This work embraces a range of environmental drivers for sedimentary processes including climate, tectonics, volcanism, and human-induced land-use change. In addition, my research and commercial activities are ongoing into techniques for seafloor characterization and quantifying sediment dispersal.
I am a paleoecologist who uses biotic and abiotic proxies preserved in lake sediments to reconstruct past environments. My particular expertise is with the Chironomidae (Class: Insecta, Order: Diptera): non-biting midges who's lifecycle is highly dependent on temperature. I am particularly interested in using paleoecology to understand both water quality over the last millenium in New Zealand and the events that characterise the last deglaciation (~20 to 10 thousand years ago) in Australasia, generally.
