I am a post-doctoral Research Associate working in the Astronomy & Astrophysics Group at the SUPA School of Physics & Astronomy of the University of Glasgow. My research has been mostly focused on the analysis of observational data of solar flares, investigating the properties of high-energy particles (through radio/microwave and X-rays data, and also computational simulations) and evolution of the flaring regions, mostly using ultraviolet/X-ray data. Currently, I am investigating the characteristics of the flaring chromosphere, through the analysis of multi-wavelength data, using computational flare models and evaluating the comparison of data vs. models, within the EC FP7 F-CHROMA project.

My publication list is available on:
