Dr Maja Cassidy is a Senior Lecturer, ARC DECRA Fellow and Scientia Fellow in the School of Physics. Her research focuses on developing new technologies that will be integrated into future quantum computing and sensor systems. She completed a Bachelor of Electrical Engineering (Hons. 1) at UNSW as a Coop scholar before moving to Harvard University, where she undertook a masters and PhD in Applied Physics in the lab of Prof Charles Marcus. After a postdoctoral fellowship at TU Delft/QuTech, she returned to Australia where she spent 5 years as a Principal Research Manager at Microsoft Quantum, where she led quantum hardware integration. She joined UNSW at the end of 2022, where she leads the QMD lab, and teaches the 3rd year course Quantum Physics of Solids and Devices.
