I am a postdoctoral researcher researching the Sun's corona, to better understand explosive events such as flares and CME's that can affect us here on Earth. One interesting avenue for remote diagnostics of the coronal plasma is the observation of magnetohydrodynamic (MHD) oscillations. I hope that studying the relationship between oscillations, plasma conditions and explosive events, space weather forecasting may be improved.
My research currently focuses on one specific MHD wave, so-called "decay-less" kink oscillations. These are observed everywhere in the corona, making them very useful for routinely diagnosing the Sun's plasma. For more details, please take a look around my site (links at top of page). Even better, pop me an email and I'd be happy to answer any questions.
Position: Postdoctoral Research Assistant

Research topics: My area of research is the study of EUV images (from SDO/AIA) of waves in the solar atmosphere, and comparison with theory and simulations in order to perform plasma diagnostics and infer local plasma conditions. Using processing tools such as motion magnification I perform in depth analysis of transverse "decay-less" kink oscillations. These may be significant for routinely measuring the magnetic field on the Sun, important for space weather forecasting; although questions about their origin remain open.
I am also currently interested in expanding the theory of wave-induced thermal misbalance on slow modes, incorporating finite-beta effects. Such slow modes act as probes into the local thermodynamic equilibrium (or non-equilibrium!) and we at Warwick are developing a new way to probe the unknown coronal heating function, one of the most important open questions in solar physics today.
