Michelle Yvonne SimmonsAOFRSFAAFRSNFTSE (born 14 July 1967) is an Australian
quantum physicist, recognised for her foundational contributions[2] to the field of atomic electronics.
Michelle Yvonne Simmons was born on 14 July 1967 in
London, to a mother who worked as a bank manager[3] and a father who worked as a policeman.[4] Simmons grew up in South-East London with an older brother.[5]
As a postgraduate at
St Aidan's College, Durham she was awarded a
PhD in 1992 for her thesis "The characterisation of CdTe-based epitaxial solar cell structures fabricated by MOVPE", with research supervised by Andrew W. Brinkman.[6][1]
In 1999, she was awarded an
Australian Research Council (ARC) QEII Fellowship and went to Australia, conducting research for four years under this fellowship.[4] She was a founding member of the
ARC Centre of Excellence for Quantum Computer Technology, and as of 2023[update] remains director of the centre.[8]
She has held several other positions over the course of her career, including:[4]
2000: Director, Atomic Fabrication Facility, UNSW
2000: Manager, Atomic Fabrication and Crystal Growth Program, Centre for Quantum Computer Technology, School of Physics, UNSW
Simmons is well-known internationally for creating the field of atomic electronics,[10] that is, building electronic devices at the atomic scale. Her research team at ARC created the first precision single atom
transistor and the narrowest conducting wires in
silicon, among other achievements.[8]
Since 2000 she has established a large research group dedicated to the fabrication of
atomic scale devices in
silicon and
germanium using the atomic precision of
scanning tunnelling microscopy. Her research group is the only group worldwide that can create atomically precise devices in silicon—they were also the first team in the world to develop a working "perfect"
single-atom transistor[11] and the narrowest conducting doped wires in silicon.[12]
Simmons has published over 400
peer-reviewed journal papers, amassing over 9,000 citations, written five book chapters, and published a book on
nanotechnology.[13]
She has also filed 44
patents and delivered over 250 invited and plenary presentations at international conferences.[8]
Simmons has resided in Australia since 1999, taking citizenship in 2007.[42]
She is married to Thomas Barlow, formerly, a
Financial Times columnist[43] and a
Fellow of
MIT and
Balliol College, Oxford,[44] now a novelist and business analyst. They have three children.[45] She says she enjoys "planning expeditions and keeping fit. But the thing that brings me the most joy is my funny husband and three adorable children".[10]
In her 2017 Australia Day address, Simmons criticised the lowering of standards in physics education in the HSC (
Higher School Certificate) curriculum, in which an effort has been made to make physics more appealing to girls by substituting mathematical problem-solving with qualitative responses, remarking that the curriculum had a "feminised nature".[18]
When Simmons was made
Australian of the Year in 2018, she spoke about the importance of not being defined by other people's expectations of you. She said, "Don't live your life according to what other people think. Go out there and do what you really want to do". She is passionate about encouraging girls to pursue a career in science and technology. "Seeing women in leadership roles and competing internationally is important. It gives them the sense that anything is possible", she said.[46]
