Professor A D Kennedy
My current research interests are Lattice Quantum Field Theory (LQFT), Renormalization Theory, algorithms for High Performance Computation (HPC), and computer algebra algorithms for tensor manipulation. I am also interested in HPC hardware and software architecture, Markov Chain Monte Carlo (MCMC) methods, and recently also in the numerical analysis for the symmetric eigenvalue problem for very large systems.
I currently teach courses on Relativistic Quantum Field Theory, Group and Team Review Project, Quantum Computing Project, and Research Skills for Theoretical Physics.
I am also a personal tutor, mainly for students on the Mathematical and Theoretical Physics MSc programmes.
