Course Director: STFC Introductory Solar System Plasmas Summer School 2018, August 27-31, 2018
Main Organiser: IAU Symposium 335: Space Weather of the Heliosphere: Processes and Forecasts, July 17-21, 2017
My Profile: I am a senior lecturer with over 20 years of research experience in solar and space physics and until early 2017 I have been holding a prestigious and personal research fellowship (STFC Advanced Fellowship 2012-2017). I am a Royal Astronomical Society (RAS) Councillor, Vice-President of Commission E3 Solar Impact throughout the Heliosphere for the International Astronomical Union (IAU), International Space Weather Initiative (ISWI) UK coordinator, member of European Space Agency’s Solar System and Exploration Working Group (SSWEG) and the UK Space Agency’s Science Programme Advisory Committee (SPAC). I have acquired my research experience and studied while residing in England, Belgium, Scotland, and prior to that France.
Research: I study our solar-terrestrial environment. I work with remote and in-situ multi-spacecraft data revealing properties measured on the Sun or in space, and I combine observations and data analysis with magnetohydrodynamic (MHD) theory. My research goal is to understand instabilities, governed by magnetized flows, common to space, solar and astrophysical plasma environments, and to develop the framework for space weather applications.
Research Interests: Solar system, geo-, astro- and space plasma physics, combining theory, observations and data analysis:
- Remote and in-situ multi-spacecraft data analysis of solar-terrestrial plasmas;
- Magnetospheric physics, e.g. Pc5 pulsations, boundary layers and solar wind plasma entry;
- Solar physics, e.g. theory of MHD waves and interpretation of coronal waves and instabilities;
- Space weather and Sun-Earth Connections.
Researh Group: This group is forming (PhD Student & Postdoctoral Fellow) and is looking to expand. I offer a research program in Heliophysics on "Multi-spacecraft investigations of solar and heliospheric plasmas".
Heliophysics is in its golden age, with an unprecedented number of satellites providing observations of unparalleled quality, either (remotely) of the Sun or (in-situ) of the solar wind. The project will be to investigate plasma and dynamical properties using the complementarities of multi-spacecraft observations. The objective is to reveal phenomena and unravel the physics governing key regions of our Sun-Earth system in the chain of space weather events that can affect our radiation environment, our communication systems and our climate. As well as joining the Centre for Geophysical and Astrophysical Fluid Dynamics, the PhD student will directly benefit from links with the Institute for Data Sciences and Artificial Intelligence (IDSAI), the Astrophysics cluster and the nearby Met Office space weather activities. This brand new PhD project will equip the student with skills suited to address future science with Solar Orbiter, the ESA mission that was launched in 2020.
Keywords: Sun, Space Weather, Data Sciences
