Hannah J. Joyce is an Australian scientist and engineer, and a professor at the Department of Engineering at the University of Cambridge.^[1] Her research specialises in the development of new nanomaterials for applications in optoelectronics and energy harvesting. She has received several awards for her work in nanowire engineering and terahertz photonics.^[2]

Joyce studied a double undergraduate degree, receiving a Bachelor of Science and Bachelor of Engineering in 2005 from the University of Western Australia,^[3] specialising in pharmacology and electrical/electronic engineering.^[4]

She obtained a Ph.D. in physics from the Australian National University in 2010, where her research focused on the growth and characterisation of III-V semiconductor nanowires for applications in optoelectronic devices. She co-authored 22 publications during her doctoral studies.

Joyce stayed at ANU until 2010 to begin her postdoctoral research in the Department of Physics at the University of Oxford.^[1] She became a lecturer at the Department of Engineering at University of Cambridge in 2013, holding a Research Fellowship from the Royal Commission for the Exhibition of 1851.^[5] In 2016, she was awarded a Starting Grant from the European Research Council for her work on nitride nanowire engineering.^[6]

She is currently a professor of low-dimensional electronics at the University of Cambridge, and her research group studies the development of new nanomaterials, such as nanowires, for applications in photonic and electronic devices.^[7] She has also been a principal investigator and co-investigator on two Engineering and Physical Sciences Research Council grants to study multiplexed quantum devices and integrated circuits.^[8]

Joyce has co-authored more than 100 publications in peer-reviewed journals.^[9]

Joyce has been internationally recognised for her contributions towards the engineering of optoelectronic devices based on nanowires. She pioneered the use of terahertz spectroscopy for contact-free electrical characterisation of III-V semiconductor nanowires, as well as developing the first ultrafast switchable terahertz polarisation modulators.^[10]
