Research Interests

My research has focused on building upon the understanding of spin-based quantum systems in the context of quantum computation, particularly focusing on the silicon-metal-oxide-semiconductor spin-qubit platforms initially developed at UNSW. I have become especially interested in determining how qubit environmental contributions can affect experimental performance, particularly when moving from singular qubit systems to multiple qubits. I am interested in concepts such as optimal qubit control and propagation of quantum information. I enjoy investigating, designing and analysing qubit mechanisms which can demonstrate robustness against system scalability.

Interesting fact

I come from a town called Orange, better known for its apples.
