Personal profile

Research Focus

My research focuses on studying the changes in the lowest regions of the Sun's, and other stars', atmospheres due to heating from solar and stellar flares respectively.

I primarily use a combination of radiative-hydrodynamic and radiative transfer codes to simulate the potential observable changes in the emission from neutral Iron (Fe I) spectral lines formed in the stars' photosphere. By analysing the changes in the line profile shapes, and particularly applying the insights models give to the factors we can't directly measure, I explore how the emergent light is formed and the key features and changes of the atmospheres' characteristics that affect observables.  

The main research outcome of my work is highlighting that the observed apparent Doppler shifts of deep-forming spectral lines can be very misleading, and even completely contradictory, to the true line-of-sight velocities within the lower atmosphere due to flare-induced emission from higher in the atmosphere. 

Interests

I am a proficient science communicator and astronomy public engager. I am the winner of the 2024 Famelab Northern Ireland science communication competition and a finalist in the UK national final. 

My primary public engagement goal is to provide accessible science opportunities to everyone, making science understandable and enjoyable regardless of an individual's background or previous experience.
