Leanne Armand




A/Prof. Leanne Armand is an expert in Southern Ocean diatom taxonomy (the identification of marine microscopic phytoplankton). She has a strong interest in the distribution of individual species related to the physical oceanic environment, and the subsequent preservation of this environmental relationship in the fossil record. She uses the records of fossil diatoms in deep sea cores between Australia and Antarctica to estimate past climatic conditions, such as sea ice extent and sea surface temperatures over the last glacial cycles (~240,000 yr). A/Prof. Armand is the new Australian and New Zealand International Ocean Discovery Program Consortium (ANZIC) Program Scientist and an Australian National University Researcher in the Research School of Earth Sciences. She was the Chief Scientist of the very successful palaeoceanographic mission to the Sabrina Coast, East Antarctica, on Australia’s new research vessel the RV Investigator (2017). She was the initiator and Director of the national Collaborative Australian Postgraduate Sea Training Alliance Network (CAPSTAN) designing a Master-level training at sea program with the Marine National Facility and on the RV Investigator (2013-2017), and was a Deputy Director of the Macquarie University Marine Research Centre, MQ Marine (2015-2016). She is a council member of the International Society of Diatom Research (2016-2019). A/Prof. Armand has succeeded in attracting over $3 Million in research funding and $8.7 Million in ship time to the Southern Ocean where she conducts her research.

Prior to her current appointment, A/Prof. Armand held post-doctoral positions at the Antarctic Climate and Ecosystem CRC in Hobart, Tasmania. While there she was the first Australian awarded an European Union Incoming Marie Curie Fellowship (FP6, 2005-07), which she undertook at the University of Marseille, France, in collaboration with Prof. Bernard Quéguiner. During this time she focused her research on the living diatom community of the Southern Ocean near Heard and Kerguelen Islands where she has contributed knowledge to the understanding of diatom community responses and the export of their carbon to the seafloor as a result of their population explosion under the annual, naturally iron-stimulated, spring bloom.  In 2007 A/Prof. Armand was awarded the Australian Academy of Science’s Dorothy Hill award for her excellence in palaeoceanographic research and also the Bigelow Laboratory’s Rose-Provasoli award. A/Prof. Armand completed her PhD in 1998 at the Australian National University under the guidance of Prof. Patrick DeDeckker and the late Dr Jean-Jacques Pichon (Univ. Bordeaux I, France). A/Prof Armand was employed by the Department of Biological Sciences at Macquarie University in 2009 as a Centre of Research Excellence (CoRE) appointee to Climate Futures at Macquarie. She most recently convened the unit “Biology in Practice” a skills-based course for 400-500 1st year biology students. She was the Director of the Marine Science undergraduate programme (2010-2013), course convenor of BIOL121 (Marine Biology and Ecosystems) and MAR201 (Introduction to Marine Science) and has been a supervisor to Merit Scholars, Master and PhD students, which continues in her new role at the Australian National University.
