Dr. Longcope conducts theoretical research into the basic physics of
magnetic fields in ionized plasmas and the application of these concepts to magnetic fields on the Sun. He has studied the storage
and release of magnetic energy in the Sun's corona through a process known as reconnection. He has also
studied the rise of slender strands of magnetic field from deep within the Sun up to the solar surface.

His research covers the physics of the solar corona and solar wind, and generally of space plasmas. He has been active in data analysis as well as theory and modelling. He has been co investigator of many experiments, among them the EUV spectrometer SUMER on SOHO and the SECCHI instrument on STEREO. He proposed the Solar Orbiter mission, which was selected by ESA to fly around 2014.
I'm interested in astrophysical fluid dynamics and magnetohydrodymanics, particularly as it applies to the interior of the sun and other stars. Most of my recent work focuses on high-resolution numerical simulations of convection, turbulence, and shear in the solar interior and the implications all this has for solar dynamo theory and for detectable surface flows such as differential rotation and solar sub-surface weather. I've also done some work on turbulence and waves in interstellar molecular clouds.
My research interests are in the solar physics, astrophysics and nonlinear wave theory. The key word in all my work is a wave (for me, it is something which can propagate somewhere). Particularly, I deal with magnetohydrodynamic (MHD) waves, which are believed to be responsible for a number of astrophysical phenomena and are observed in the atmosphere of the Sun, solar wind and magnetosphere of the Earth (However, it seems that they can be found everywhere in the Universe, where there is a plasma penetrated by the magnetic field). Propagating through an inhomogeneous, non-stationary, nonlinear and sometimes active medium, such as the space plasma, MHD waves gain extremally interesting new properties leading to a number of amazing physical phenomena, like the existence of solitons, negative energy effects, self-organisation and many others.

He focuses his research on modeling of MHD processes in the solar interior, coupled models of the differential rotation, meridional flow, and large-scale dynamo, addressing non-kinematic effects and cycle variations of the solar differential rotation (torsional oscillations).
My research focuses on astrophysical fluid and plasma dynamics, notably solar physics, turbulent convection, MHD and dynamo theory, accretion disk turbulence, microinstabilities in magnetized plasmas, and pulsations of magnetized stars.
My main research interests are three-dimensional simulations of convection and magneto-convection in the Sun, and one-dimensional radiation-hydrodynamics of waves and non-equilibrium radiation in the solar atmosphere.
Theory and observations of magnetohydrodynamic wave phenomena in the solar corona and the determination of physical coronal plasma parameters from observations of MHD wave characteristics. Application of image-analysis techniques to solar image data.
My professional interests include solar coronal physics, coronal mass ejections (CMEs) and space weather, which includes a heavy dose of halo CMEs and their heliospheric characteristics and geoeffectiveness.

Research Interests:
My primary research interests involve observational studies of the outer atmosphere of cool stars using UV, EUV, X-ray, and radio emissions from these stars. I am also interested in the local interstellar medium and its interactions with the winds of late-type stars. The Sun certainly falls within my purview, as I have analyzed observations of the Sun and heliosphere, in addition to my work on cool stars in general.

Research Interests:
My main interest is magnetohydrodynamics (MHD), particularly the structure and evolution of the Sun's magnetic field. I focus on problems which are nonlinear, three-dimensional, time-dependent, or all three. I apply a mixture of numerical and analytical modelling.
