Professor Stan Cowley was educated at Caludon Castle School, Coventry, and Imperial College, London, where he graduated with first class honours in Physics in 1968.  He subsequently undertook post-graduate studies at Imperial under the supervision of Prof Jim Dungey, being awarded a PhD in 1972 for his thesis entitled Self-Consistent Models of Magnetic Neutral Sheets.  Following a Visiting Fellowship at the University of Colorado in 1972-3, he returned to post-doctoral studies at Imperial, being awarded a SERC Advanced Fellowship in 1977, a Lectureship in 1982, and being promoted to Reader in 1985 and Professor in 1988.  He became Head of the Space & Atmospheric Physics Group at Imperial in 1990.  In 1996 he moved to the University of Leicester, succeeding Prof Tudor Jones as Head of the Radio and Space Plasma Physics group, where he remains to date.  He is the author or co-author of ~400 research publications in the refereed scientific media.  He was awarded the Chapman Medal (1991) and Gold Medal (2006) of the Royal Astronomical Society, the Julius Bartels Medal (2006) of the European Geophysical Union, and was elected a Fellow of the American Geophysical Union (1995).  In 2011 he was also elected a Fellow of the Royal Society of London.

Research interests

My research interests have centred on the physical processes that shape the outer plasma environments of Earth and the magnetised planets, undertaken through a combination of theoretical studies and the analysis of relevant data.  The principal interactions are those between the flowing shocked solar wind and the planetary magnetic field at the magnetopause boundary, and the further interactions that occur between the magnetospheric field/plasma and the planetary ionosphere and upper atmosphere.  My early interest focussed on the role of magnetic reconnection in mediating solar wind-magnetosphere coupling at Earth.  More recent work has centred on the dynamics driven in outer planet magnetospheres through coupling to the rapidly-rotating planetary atmosphere.  Relevant data are obtained through my participation in international space missions, auroral observations of outer planets using the Hubble Space Telescope, and use of ground-based radars at Earth.  Currently-active spacecraft Co-Investigator roles include the ESA Cluster four-spacecraft terrestrial mission and the NASA Cassini Saturn-orbiter mission.  I am also involved as Co-Investigator in the NASA Juno mission, currently en route to Jupiter, where it will be inserted into polar orbit in 2016.


Since becoming Professor Emeritus in 2013, teaching has concentrated on post-graduate studies including PhD student supervision.  A postgraduate course is taught in alternate years on Kinetic Theory of Collisionless Plasmas.
