### Research Interests

Quantum walks, whilst a relatively new area of research, have become an incredibly exciting ﬁeld due to their potential applications in quantum information theory and quantum simulations; perhaps even leading to the future production of quantum computers and with that the possibility of revolutionizing the way we carry out computation and information processing.

As part of my doctoral thesis, I presented a software package for simulation of multiparticle continuous-time quantum walks (CTQWs) using high performance computation, and detailed a method of systematic dimensionalty reduction for fermionic CTQWs. This requires a high degree of anaytic and computational work, and enabled me to develop a extensive expertise using high performance computing techniques. With the growing importance of high performance computing in physical research, these skills have enabled me to cross disciplines, and perform magnetisation dynamic simulations that could lead to signiﬁcant advances in manufacturing non-volatile memory storage devices.

I am also interested in the applications of quantum walks, specifically in regards to complex network analysis. One such application is in network centrality - an algorithm that underpins Google, the biggest and most well-known search engine. Part of my research has involved designing a quantum centrality algorithm that works on directed network structures - this algorithm is utilized in the first successful physical quantum centrality implementation.
