Prof Tim R. Morris is professor of theoretical physics, Fellow of the Institute of Physics, Fellow of the Higher Education Academy, and Head of the Theoretical High Energy Physics theory group, one of the largest groups in the UK. He has previously been both head and deputy head of department. For the year 2017/18, Tim held a Royal Society Leverhulme Trust Senior Fellowship, devoted full time to research into the Wilsonian renormalization group in quantum gravity. His recent work on asymptotic safety solved for the first time the fixed point structure in the infinite dimensional f(R) approximation. He has led in developing these approximations in particular in the large curvature domain. He has begun the development of a manifestly diffeomorphism invariant and background independent formalism. His recent work has demonstrated that there is much more to the renormalization group properties of quantum gravity than has been assumed, in particular even for perturbative quantum gravity.
Tim's very first research was in Quantum Chemistry whilst he was still at school, and later when he was a Scholar at Cambridge University. His PhD research was on Instantons in Super Yang-Mills, at Southampton. In 1985 he won a prestigious Harkness Fellowship to do post-doctoral research at Princeton, NJ USA. While there, he was amongst the first to apply Polyakov's new methods to open strings, and to work on Witten's string field theory. In 1987 he returned to a lectureship in Southampton. Following work at Fermilab on research leave in 1989, he discovered a way of using complex matrix models to formulate and solve various simple string theories non-perturbatively. In 1992 he won simultaneously both a CERN fellowship and SERC/PPARC Advanced Fellowship. During these fellowships, he developed the Wilsonian/exact renormalization group into a powerful methodology, both calculationally and conceptually. He discovered, independently the flow equation for the effective average action proposed by Wetterich a few months previously (which was in turn a rediscovery of the flow equation first introduced by Nicoll and Chang in 1977), proposed the derivative expansion (now established as one of the most powerful of approximation methods in this framework), showed how to solve for fixed points and quantised eigenoperators in these infinite dimensional approximations, and recover analytically the correct behaviour in terms of renormalised couplings. He developed a manifestly gauge invariant exact renormalization group, a long standing unsolved problem, which at the same time solved other long standing problems: continuum computations without gauge fixing, and furnishing a physical gauge invariant regulator.
Tim has worked on a number of other areas, including MHV rules, beyond the Standard Model, and cosmology, held a number of other grants and fellowships, and has had extensive teaching experience at both the undergraduate and graduate level. He is an accomplished pianist; he obtained a diploma from the Royal Academy in 1980, won the audience prize in the Pianist-Yamaha competition for outstanding amateurs in 2005, and has performed several concertos.

Professor Christian Knigge graduated with a BSc (Hons) in Physics with Computer Science from the University of Southampton and then obtained a DPhil in Astrophysics from the University of Oxford. He was a postdoctoral fellow at the Space Telescope Science Institute in Baltimore and was then awarded a Hubble Fellowship, which we held at Columbia University in New York. He returned to the University of Southampton in 2000 and is now a Professor in the department.
Research
Research interests
Christian has broad research interests that include accretion physics on all scales, binary evolution, compact objects (white dawrfs, neutron stars and black holes), globular clusters, radiative transfer and (astro)statistics.
Teaching
I currently teach the first-year core module PHYS1201 "Physics Skills: Programming and Data Analysis", as well as PHYS2011 "Design and Observation in Astronomy", which includes a 2-week field trip to Tenerife during which we spend 1 week at the Observario del Teide carrying out astronomical observations.

After completing his PhD at University College London's Mullard Space Science Laboratory, he was a postdoctoral researcher at the University of Leicester. He joined the University of Southampton as an STFC Ernest Rutherford Fellow (2013-18). His research interests are in large-scale solar wind/magnetosphere/ionosphere coupling, and he has extensive experience in the use of in situ satellite data, radar data and global-scale auroral imaging to understand the dynamics of the region of space occupied by the Earth’s magnetic field (the magnetosphere) and its influence on the upper layers of the Earth’s atmosphere (the ionosphere). In recent years, his research interests have broadened to include global scale magnetospheric dynamics during periods when the interplanetary magnetic field is northward, which has led to several key publications on this topic in the Journal of Geophysical Research, Geophysical Research Letters and Science magazine. Community roles include membership of MIST Council, the UK representative body for Magnetospheric, Ionospheric and Solar Terrestrial physics (2011-2017), and he is a member of STFC’s Astronomy Grants Panel (2017-).

Dr John Coxon is a postdoctoral research assistant in the Space Environment Physics group, working with Dr Rob Fear. His research interests include currents in near-Earth space known as Birkeland currents. He also studies transpolar arcs (TPAs) and flux transfer events (FTEs), two signatures of the processes by which the Sun and Earth's magnetic fields interconnect.
John is the lead of the Planeterrella public engagement programme, and has experience teaching in both schools and universities. He is also on MIST Council, the governing body of an organisation representing Magnetosphere, Ionosphere and Solar-Terrestrial researchers in the UK.
