PhD BSc (Hons)


A/Prof. Armand is the new ANZIC (Australian and New Zealand International Ocean Discovery Program Consortium) Program Scientist and an ANU RSES researcher. She is currently a council member of the International Society of Diatom Research (2016-2019) and the representative for ANZIC on the National Marine Science Committee.

Prior to her current appointment, A/Prof. Armand was a member of the Dept of Biological Sciences at Macquarie University (2009-2017). At Macquarie, A/Prof. Armand established and convened the unit "Biology in Practice" a skills-based course for 1st year biology students (2016-2017). 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 was a supervisor to Merit Scholars, Master and PhD students. A/Prof Armand was the first 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 on the RV Investigator (2013-2017), and was a Deputy Director of the MQ Marine Research Centre (2015-2016).

A/Prof. Armand has also 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 because of their population explosion under the annual, naturally iron-stimulated, spring bloom. 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).

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. In 2014, she received an U.S. Antarctic Service Medal for service on the U.S-led Sabrina Coast Mission on the RVIB N.B. Palmer.



Research interests

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 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). Her research is now concentrated on the investigation of geochemical and genomic markers derived from diatoms in the sea ice environment of the Sabrina Coast.
