Personal details

  • BSc (Hons), PhD (Leicester)

I studied Physics with Astrophysics at the University of Leicester, graduating in 1990, before undertaking a PhD in the Radio and Space Plasma Physics (RSPP) Group, under the supervision of Professor Mike Warrington and Professor Mark Lester.

I subsequently held post-doctoral research positions in RSPP until 2000 when I became a Visiting Research Fellow at the National Institute for Polar Research in Tokyo.

I was appointed as a Lecturer in the Department of Physics and Astronomy at the University of Leicester in 2001, being promoted to Reader in 2007 and gaining a Chair in 2011. I was Senior Undergraduate Tutor in the Department of Physics and Astronomy from 2013 to 2015. I am now considerably older than my photograph would suggest.

Between 2013 and 2019, I held a visiting Adjunct Professor position at the Birkeland Centre for Space Sciences, University of Bergen, Norway.

I was Secretary for Magnetospheres in the Division of Solar-Terrestrial Sciences of the European Geosciences Union from 2006 to 2012 and was the principal investigator for ground-based support of the European Space Agency Cluster mission from 2003, for which I was awarded an ESA award for 'outstanding contributions to the Cluster mission' in 2005.  I have been a member of the SCOSTEP Advisory Committee on 'Future Research Directions' and Reporter for 'Global Magnetospheric Dynamics' of IAGA Division III.

I was awarded the European Geophysical Society's Young Scientist's Publication award in 2001, and the Royal Astronomical Society's Chapman Medal for 'outstanding contributions to Solar-Terrestrial Physics' in 2013. I am most proud of my award from the Space Physics and Aeronomy Section at the 2007 American Geophysical Union Meeting for 'Paper with Cutest Subtitle'.

I have been an Associate Editor of Geophysical Research Letters (2007-2009) and the Journal of Geophysical Research (2010-present), both published by the American Geophysical Union.

I am also currently a Topical Editor for Annales Geophysicae (2014-present), published by the European Geosciences Union. From 2011-2014 I was the coordinator of the EU-funded, Seventh Framework Programme (FP7) European Cluster Assimilation Technology (ECLAT) project.

I was lead proposor of the Ravens mission concept to the European Space Agency's M3 spacecraft mission call in 2010, the leader of the ESA science definition team for KuaFu-B from 2011-2012, and the lead proposer of Ravens to the 2015 M4 call. Not having learnt my lesson, I was then lead proposer of JANUS to M5.

Research

My research interests centre on solar wind-magnetosphere-ionosphere-atmosphere coupling, that is the mechanisms by which energy is coupled from the solar wind into the near-Earth environment, the resulting behaviour of the magnetosphere/ionosphere system, and the impact on the environment and technological systems. The expanding/contracting polar cap paradigm is used as an underpinning framework for understanding magnetospheric dynamics: terrestrial magnetic flux is connected and subsequently disconnected from the interplanetary medium by magnetic reconnection at the dayside magnetopause and in the magnetotail, respectively, in a process that is depressingly akin to balancing the incomings and outgoings of a bank account.

My main observational tools are the SuperDARN radar network, space-based auroral imagery, and the AMPERE technique that exploits magnetometer measurements from the 60+ satellites of the Iridium telecommunications constellation.
