I conduct research focused on the observation and analysis of radio emissions from the Sun, under the supervision of Professor Eduard P. Kontar.  I am particularly interested in the physical mechanisms defining the morphological characteristics of Type II radio bursts which are excited by shock waves associated with Coronal Mass Ejections (CMEs).  I also study the radio-wave scattering effects in the solar corona to better understand the observed radio emissions.  I have utilised data from several instruments including SDO/AIA, SOHO/LASCO, GOES/XRS, and LOFAR.
