Almost 3,5 years of research work, 5 countries where it was conducted, 230 pages of the doctoral dissertation, 40 mins of defence presentation, many sleepless nights but also gratitude that is impossible to quantify to everyone who supported me along the way and participated in my studies! In this post I briefly (less than 230 pages) discuss what I have been working on, how was this unique experience for me, and what I have learned and obtained during those years. Of course, there is also a “future work” section.
