The launch of SoHO (Solar and Heliospheric Observatory) in the late nineties marked the beginning of a golden age in solar physics. I became fascinated by the wealth of possibilities involved in solar physics research and did a PhD at Sheffield University.

In 2003 I moved to Armagh Observatory to work as a PDRA. In 2006, I was awarded a Leverhulme Trust Early Career Fellowship at Sheffield University.

Since 2010 I am a lecturer in the Physics Department at Aberystwyth University. Apart from teaching duties I am involved in outreach and editing the departmental web pages.



My research is primarily concerned with the physics of space plasmas and solar/stellar coronae. The study of processes occurring in such systems is important for understanding the Sun and the stars, predicting space weather and understanding the plasma behaviour in laboratory devices. My research involves modelling of solar coronal magnetic structures and processes which heat and maintain the coronal plasma at multimillion degree temperatures; studying fundamental plasma processes such as waves and instabilities; determining the physical parameters of solar magnetic structures through spectroscopic and imaging observations. In my observational work I mainly use data from space missions such as SoHO, TRACE, Hinode, and the recently launched SDO satellite.
