Doctor of Philosophy (National University of Singapore)
During 1999 to 2003 Dongchen Qi studied physics in Peking University for his undergraduate education before he moved to Singapore. After receiving his PhD degree in surface science from the National University of Singapore in 2009, he spent another two years as a research fellow at the same institute. In 2012, he joined the Institute of Materials Science and Engineering (IMRE) as a staff scientist working on organic electronic devices. He took up a faculty position as a lecturer in physics at La Trobe University in 2013. In 2017, Dr. Qi was awarded the prestigious ARC Future Fellowship to develop high-performance diamond surface electronics and quantum devices. In 2018, He joined the Queensland University of Technology as a Senior Lecturer and was subsequently promoted to Associate Professor in 2020. Dongchen's research interests lie in the area of experimental condensed matter physics and material physics, focusing on creating, understanding, and controlling at nanoscale the surfaces and interfaces of functional materials to develop new technologies and material platforms for the next-generation devices. He is particularly interested in using advanced synchrotron light to examine important interface phenomena and physics essential to enable electronic devices based on emerging materials including diamond and organic semiconductors. Dongchen has published more than 110 articles in internationally refereed journals including Nature Nanotechnology, Nature Materials, Physical Review Letters, Journal of the American Chemical Society, and Advanced Materials, with an H-index of 33 (Google Scholar).
