Finally, my PhD research is completed with the submission of the hardbound copies of the thesis after addressing the comments in the thesis defense. On 4th Feb I collected the hard-bound copies of the PhD thesis and submitted them to the research office at Coleraine. It turned out to be a long day, but I could have managed better if I properly checked the train and bus timings. Anyway, it was a big relief to get it over with after all these years.
