# Nick Mortimer

Nick Mortimer is a New Zealand geologist, who has made a name for himself with his work on Zealandia.
Nick Mortimer was born in England and now lives in Dunedin, New Zealand. He studied geology and graduated with a Bachelor of Science with distinction in 1980. He then completed a PhD in geology and received his doctorate four years later.
Mortimer published his first papers in 1986/1987 while working at the Department of Geological Sciences at the University of British Columbia in Vancouver, Canada. He later has been working as a petrologist at the Dunedin Research Centre of the Institute of Geological and Nuclear Sciences (GNS Science) since 1994, where he is one of the "Principal Scientists". During his career, he has conducted research in Antarctica, Australia, Canada, the Pacific islands, the United States, and many areas of New Zealand.
Mortimer became known worldwide as the lead author of the article "Zealandia: Earth's Hidden Continent", which he published 2017 together with ten other scientists in the March issue of GSA Today, a scientific journal of the Geological Society of America and with which he received a broad response in the media worldwide.
