Theo Murphy international scientific meeting organised by Dr Ineke De Moortel and Professor Philippa Browning.
It has been known for more than half a century that – surprisingly - the Sun’s atmosphere is far hotter than its surface. This meeting will be dedicated to the long standing ‘coronal heating problem’, bringing together theoretical experts with modellers and observers to assess current understanding and debate the most promising strategy to ensure further progress.

Dr Ineke De Moortel, University of St Andrews, UK
Biography not yet available
Professor Philippa Browning, University of Manchester, UKOrganiser
Philippa Browning graduated with a degree in Mathematics from Cambridge and then obtained a PhD in Solar Physics at the University of St Andrews. Subsequently, she lectured in Physics at UMIST and is now Professor in the Jodrell Bank Centre for Astrophysics at the University of Manchester. Her research field is theoretical plasma physics, with applications both the solar atmosphere and to magnetically-confined fusion plasmas. Her recent research focuses on the process of magnetic reconnection and its role in energy release and particle acceleration. The main aims of this research are to understand how stored magnetic energy is released in solar flares, and to explain how the solar corona is heated to millions of degrees. She is a Fellow of the Institute of Physics, and chairs the IOP Plasma Physics Group. She is Editor of “Journal of Geophysical Research – Space Physics”.
Dr Jim Klimchuk, NASA Goddard Space Flight Center USAe coronal heating problem: current understanding and future directions
James Klimchuk is a research astrophysicist in the Heliophysics Division at NASA’s Goddard Space Flight Center. He specializes in studying the solar corona—the multi-million degree outer atmosphere of the Sun that is the primary source of “space weather” that can wreck havoc with technological systems here at Earth. Of particular interest is the question of how the corona is heated to its extreme temperatures. Dr Klimchuk approaches research problems with a close coordination of theory and observation. He has used data from every solar mission ranging from SMM, to SOHO, to SDO.
Dr Klimchuk has held numerous elected and appointed leadership positions, including current President of the Space Physics and Aeronomy Section of the American Geophysical Union, Chair of the Solar Physics Division of the American Astronomical Society, and President of Commission 10 of the International Astronomical Union. He currently chairs the committee that advises NASA on solar and heliospheric physics.
Dr Klimchuk is an Honorary Fellow of the Royal Astronomical Society and recipient of the John C Lindsay Memorial Award for Space Science and NASA Outstanding Leadership Medal. He earned a BA in physics from Kalamazoo College and a PhD in astrophysics from the University of Colorado in 1985. He worked at Stanford University and the Naval Research Laboratory before joining NASA.

Professor Peter Cargill, Imperial College/University of St Andrews, UKModels of nanoflares: MHD and plasma response
Peter Cargill is currently Emeritus Professor of Physics at Imperial College and Honorary Professor at the University of St Andrews. Since his PhD in 1981, he has worked on solar and space plasma physics, leading to 165 publications. In particular, his work since the early 1990s on nanoflare models for solar coronal heating has been very influential in the current direction of the topic.
Dr Inigo Arregui, Instituto de Astrofisica de Canarias (IAC), Spain Magnetohydrodynamic wave heating of the solar atmosphere
Dr Arregui is an astrophysicist with expertise on theoretical magnetohydrodynamics (MHD), a union of fluid dynamics and electromagnetism to study the dynamics of magnetised plasmas in astrophysical settings. He obtained a PhD in Physics at Universitat de les Illes Balears (Spain, 2003) with a thesis on MHD waves in the solar atmosphere. He has carried out research in Spain and Belgium, as a postdoctoral researcher; and in Japan, as visiting associate professor. At present, Dr Arregui holds a enure-track position at Instituto de Astrofisica de Canarias (Spain).
His research is focused on the interpretation and modelling of MHD wave activity in the solar atmosphere, the design of inversion and model comparison tools for remote sensing of the physical conditions and the dynamics of solar atmospheric plasmas, and the study of wave based plasma heating mechanisms. He aims at further developing the fields of seismology and wave heating of the solar atmosphere in combination with observations from space solar missions.

Professor Eric Priest FRS, University of St Andrews, UKClosing address
Eric Priest completed his PhD thesis with TG Cowling at Leeds in 1969, having moved to a tenured position at St Andrews University in 1968. He helped build up the Solar MHD group there and is now an active emeritus professor.
He has edited 15 books and written over 450 research papers. His earlier book Solar Magnetohydrodynamics (1982) has been completely rewritten from scratch to be reborn as Magnetohydrodynamics of the Sun. Honours include being elected a Fellow of the Royal Society (2002), and being was awarded the Hale Prize of the American Astronomical Society (2002) and the Gold Medal of the Royal Astronomical Society (2009). Hobbies include singing, playing bridge, climbing hills, keeping fit and enjoying his family. He also has an interest in issues of science and religion.
