Petra Kohutova successfully defended her PhD thesis on Magnetohydrodynamic Oscillations in Solar Coronal Rain on Monday 14 May 2018. The thesis examiners were Profs Duncan Mackay (St Andrews) and Tony Arber. In her thesis, Petra investigated oscillatory phenomena in cooling loops in the solar corona in observations from space-born instruments and ground-based observatory and modeled them using MHD simulations with the Lare code. Petra's supervisor was Dr Erwin Verwichte. From her PhD work, she produced four refereed articles as a first author and she contributed to two more as a co-author.
