Prof. Yun received her PhD degree from the Xian Jiaotong University in 1997. She has since held the AIST fellow and STA Fellow positions at the National Institute of Advanced Industrial Science and Technology (AIST), Kyushu, Japan (1998-2001) before the commencement of her Postdoctoral Fellow position at the Australian National University in 2001. She is currently a tenured academic staff as a chair Professor, and the Head of the Functional Materials Research Group at the Australian National University. She was awarded fellowships of the AIST (1998-1999) and the STA(1999-2001, now renamed as the Fellow of JSPS) in Japan, the Australian Research Council (ARC) Queen Elisabeth II (2006-2010) and ARC Future Fellow (2011-2016) in Australia. She is a fellow of the Australian Institute of Physics (FAIP). She is a national board member and a Certified Materials Professional (CMatP) of the Materials of Australia (MA). She is also a member of the Society of Crystallographers in Australia and New Zealand (MSCANZ) as well as the Society of Australian Ceramics.
Prof. Yun's group aims to use materials chemistry as a tool to design and develop novel functional materials for uses in electronic components, sensors, various catalysis technologies for waste water treatment, solar and H2 energy generation, storage and recoveryas well as their utlise. Up to now, she has published 15 patents, 4 books and 151 articles (such as Nature Materials and Advanced Materials).
