Tim Naish is a Professor in Earth Sciences and was Director of the Antarctic Research Centre at Victoria University of Wellington until 2017, when he took up a RSNZ James Cook Fellowship. His research focuses on past, present and future climate with specific emphasis on how the Antarctic ice sheets respond to climate change and their influence on global sea-level. He has participated in 14 expeditions to Antarctica and helped found ANDRILL, an international Antarctic Geological Drilling Program. He is co-chief officer of the Scientific Committee on Antarctic Research, Past Antarctic Ice Sheet strategic research programme, and was recently appointed to the Australian Government’s National Advisory Committee on Climate Science. He was Lead Author on the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report. He developed and co-leads the MBIE-funded NZ SeaRise Programme, which is improving location-specific sea-level projections for New Zealand, by taking into account latest polar ice sheet contributions and vertical land movements. He has received the New Zealand Antarctic Medal, the Martha Muse Prize for Antarctic Science and Policy and is a Fellow of the Royal Society of New Zealand.
