ACADEMIC STAFF |
John Carroll is an Emeritus Professor and Life Fellow of Queens' College having worked from 1967 in the Engineering Department variously as a Lecturer, Reader, Professor, Head of Electrical Division, Chairman of the Council of the School of Technology. He formally retired in 2001 but still enjoys some research and teaching and helping research students with mathematical problems. He is a Fellow of the Royal Academy of Engineering. Past research has covered microwaves, microwave devices, semiconductor devices and semiconductor lasers. Current research looks at fundamentals with applications of Clifford and Geometric Algebra to Maxwell's equations and signal processing along with speculative interpretations of classical Maxwell's equations as providing photon like resonances: Maxwellian photonics. Professor Carroll helps with the Division B 1st year Research and Communication Club and a 3rd year undergraduate project.
