It is very important for a PhD student to meet different people, research groups, and labs, in order to gain other work perspectives and develop some networking. As my second supervisor, Prof. Rein Ulijn , was invited to be the head of the Nanoscience Initiative in the new Advanced Science Research Center of the City University of New York (CUNY) , I have had the opportunity to go to New York and enjoy my time at one of the leading universities in the other half of the globe. I have spent six weeks in a brand new, top quality research center at the end of 2014.
