Prof David Berman
My main research interests are in M-theory, the nonperturbative version of string theory. The extended objects in M-theory are membranes and five-branes. They are related to strings and D-branes in string theory via dimensional reduction. Over the last few years my research has been devoted to understanding the interactions of these branes. Mainly this is through studying how membranes end on fivebranes. My other interests over the years have been varied and include: Holography and the AdS/CFT coresspondence; noncommutative geometry; and S-duality in gauge theories. Recently I have been interested in backgrounds to string theory that are intrinsically stringy in origin and not just solutions to supergravity; these go by the name of T-folds.

Prof David Burgess
I am interested in how we can use plasma physics to study natural plasmas, such as the solar wind which blows through the Heliosphere. The space environment motivates much of my work, because we can measure these plasmas in situ, with a spacraft acting like a probe into the plasma - getting ground truth that is practically impossible for other distant astrophysical objects. At the same time what we learn from solar system plasmas can be applied to remote astrophysical environments such as super nova remnant shocks and the interstellar medium. This area of research depends on data from international space missions supported by ESA and NASA, so I have collaborative links with groups across Europe and the USA.

Prof Bernard Carr
I am interested in cosmology and relativistic astrophysics, the early universe, primordial black holes and Population III stars. Other fields of interest include dark matter, cosmological solutions of Einstein's equations, the anthropic principle, the Andromeda galaxy and the AGAPE project.

Prof Carl Murray
I am interested in all aspects of the dynamics of planetary systems, from the orbital evolution of dust particles to the stability of planetary orbits. My research in recent years has been dominated by work on Saturn's rings and their gravitational interaction with the small natural satellites orbiting nearby. In particular I have been fascinated by Saturn's F ring as I work with colleagues to understand its bizarre appearance. I have been a member of the Imaging Science Subsystem Team on the Cassini-Huygens mission to Saturn and I have worked on the project since I was selected in 1990.

Prof Richard Nelson
My research is focussed primarily on the theory of planet formation, with particular emphasis on understanding how planets and planetesimals interact with the protoplanetary discs within which they form, and how this interaction affects the formation and global architecture of planetary systems. Other areas of interest include the development of models to explain the current data on extrasolar planets, the dynamics of astrophysical discs, and numerical astrophysics.

Dr Alexandre Polnarev
My main research interests lie in applying the General Relativity to Astrophysics, Cosmology and to both space and earth-born experiments. Other areas of interest include the early universe, supermassive binary black holes and their interaction with stars and accreting discs and cosmic microwave background radiation (CMBR).

Dr Sergei Vorontsov
My research is predominantly concerned with solar and stellar seismology, though I also have an interest in inverse problems and image restoration.

Dr John Donnison
My research areas include solar system dynamics, comets, asteroids, extrasolar planets and Kuiper belt objects.

Dr James Cho
I am interested in planetary formation and planetary atmospheres, linking in to my research on astrophysical fluids, the Solar System and accretion discs.
