Hongyang Ma completed his PhD in the School of Materials Science & Engineering at UNSW Sydney, where he studied noval nanoparticles for biomedical application and interfacial reactions by using density functional theory (DFT). He then joined the School of Physcis at UNSW Sydney as a postdoctoral research associate in Nov. 2020. His work is using theoretical simulation to investigate the electronic properties of shallow donors in silicon to help design and optimize high-performance quantum computing devices.
