Like all things in life, the PhD experience will definitely be better when the candidate is better supported.
Science has known no borders in terms of countries and cultures. Like music, science unites people from all walks of life, regardless of your upbringing and cultural background. Since I have set my eyes to pursue the journey of research, working in a multicultural setting is the icing on the cake to my research training as a scientist.
I find that the most challenging aspect of being a PhD research candidate is not just the research work itself, but also the people who you work with.
