    Brief Research Statement

     

    Dr. Alexander's main area of interest is the study of the dynamic solar corona via the analysis and theoretical interpretation of thermal and non-thermal radiation. His primary contributions have been in the area of solar flare and CME physics where he has developed theoretical models for the production of gamma-rays, hard X-rays, and soft X-ray line broadening. Currently, he is involved with a number of projects relating to understanding the initiation and evolution of solar flares and CMEs by exploring particle production in association with, magnetic topology, helicity injection and filament eruptions. He has recently led a study investigating the long-term behaviour of solar active regions in their build-up to large Solar Energetic Particle (SEP) events. 


    Dr. Alexander has recently started exploring a number of other areas including star-planet interactions with a focus on apply what we learn in the solar system to other extrasolar systems and to the development of novel instrumentation for earth observing.


    Dr. Alexander is working with colleagues in the Department of Engineering to evelop a novel snapshot hyperspectral imager for unique earth observation applications.

     

    Research Interests

     

    Star-planet interactions: study of the space physics of exoplanet systems and in particular the magnetic interaction between the planets and their parent stars.


    Flares/CMEs: Energetic particle acceleration and transport; flare energetics and dynamics; thermal/non-thermal evolution; CME initiation; CME acceleration and low coronal evolution; filament eruptions and their relation to CMEs; role of sunspot rotation in creating and evolving sigmoid active regions prior to eruption; role of helicity in eruption of CMEs.


    Active Region Evolution: Role of twist and writhe helicity in the dynamical evolution of sunspots, analysis of sunspot and sunspot group rotation, statistical studies of flare producing magnetic configurations, development of source conditions in the build-up to large Solar Energetic Particle events.


    Coronal Heating: Investigation of coronal heating using data from SXT, TRACE, SOHO and STEREO; application of hydrostatic and hydrodynamic loop models to explore emission characteristics in corona; coupling of sub-photospheric physics via magnetoconvection models to coronal physics via hydrostatic and hydrodynamic loop modeling.


    Solar Energetic Particles (SEP): Exploring the solar source conditions governing the spectral distributions of high energy particles observed at 1 AU.


    Active region simulation and modeling: Simulation of EUV and Soft X-ray emission in active regions, particularly for studying coronal heating and to provide simulated data for application to image reconstruction techniques for STEREO mission,


    Stellar Cycles: Exploration of soft X-ray emission from Sun as a proxy for other active stars and, in particular, what we can learn about the apparent lack of stellar cycles in Sun-like stars.


    Laboratory astrophysics: Experimentation in laboratory of solar phenomena, particularly dynamic consequences of the interaction of magnetic plasmoids with the ambient medium; application of these results to coronal jets and CMEs.


    Magnetic reconnection: Observational evidence for presence of reconnection in solar atmospheric phenomena; examination of reconnection rates in the solar atmosphere and comparison with prevailing theories.


    Solar Sails (solar and magnetospheric missions): Application of novel vantage points attainable by solar sails to explore solar and terrestrial physics domains not easily accessible with current propulsion technologies (e.g. out-of-ecliptic missions
