“I had the opportunity to supervise an amazing student, extremely motivated, very skilled, professional, and trustworthy. She designed an entire study on her own and managed to program a complex virtual reality task”.

Research at Leiden University: “Taking part to the STREAM programme had been a great opportunity to work in a true research project inside an international research group. This experience not only made me grow up under an academic point of view, but also gave me the opportunity to discover a new country and to meet people from all over the world”.

Research at University of Zurich: “The STREAM programme offered me the opportunity to experience research first-hand, which really helped me in discovering my own passions and qualities. I am really grateful that I got the chance to take part in an ongoing research project as a fresh BSc graduate. The experiences in the lab have given me a solid impression of what work in a biomedical research lab is like, and this helped me a lot in the choice for a master's degree. I have a much more realistic view of what life as a PhD student is like, and I now know better what to expect if I decide to continue in research”.
