Dr Nguyen received his bachelor degree in electrical engineering from Portland State University, Oregon in 2011 with a GPA of 3.97/4.0. From 2011 to early 2013, he was a product yield engineer at Intel where he received the Intel Global Test Manufacturing Group (TMG) Excellence award in Q4, 2012.
In 12/2016, Dr Nguyen received his PhD in engineering (photovoltaics) from the Australian National University (ANU) under the supervision of Professor Daniel Macdonald. In 2017, he was a visiting scientist at the United States' National Renewable Energy Laboratory (NREL). Currently, Dr Nguyen is a senior research fellow and senior lecturer at the ANU and the Editor of the IEEE Transactions on Electron Devices. He received CECS's Dean Award for Excellence in Supervision in 12/2018, was among the top four supervisors nominated for Vice Chancellor's Award in the same category in 02/2019, and received the ANU-wide recognition Supervisor of the Month 02/2020. He also received CECS Dean's Award for Remote Teaching in 08/2020 in both individual and course categories.
The central idea of Dr Nguyen’s research is to advance solar energy technologies through knowledge and scientific discoveries and technological inventions. His research spans from the fundamental to the applied. His team explores the fundamental properties of light-matter interactions in solar energy materials and devices under various conditions. The team works to uncover the relationship between absorbed/emitted light and important properties of the materials and devices, including optical, electrical, chemical, and structural properties. By exploiting these phenomena, the team develops novel device concepts, advanced characterization techniques, and defect engineering routes with applications to renewable energy and material science. His team's research has been featured by over 100 media channels worldwide. He has published 74 peer-reviewed journal articles in various reputable journals.
