Engineer or musician? When he was young, Tristan Gilet was equally attracted by science and the piano. Science won in the end even though he continues to play the piano, mainly jazz. In 1999, he started physical engineering studies at the University of Liege, which he combined with a degree in aeronautics completed at SupAéro in Toulouse. In 2005, he then began a PhD thesis on the dynamics of water drops at the GRASP under the supervision of Nicolas Vandewalle. He then moved to MIT in 2009 to teach mathematics and mechanics while conducting his research work. His encounter with Lydia Bourouiba influenced his research direction. He was then appointed as an assistant professor in September 2011 at the University of Liege, where he created the Microfluidics Lab one year later within the Faculty of Applied Sciences.
