The Vietnamese student was run over by a Piccadilly Line train at Earl's Court station - an incident which also left 17-year old Queen's Park Rangers (QPR) footballer Harry Smart in hospital.
Three of QPR's youth-team players were arrested and released on bail over the incident.
Carol Mancke, Vu's course director, described the popular student as 'exceptional' and well liked by everyone on the campus.
She said: 'Vu was a student who showed great promise and potential.
'We had no hesitation in offering him a place and were extremely impressed by the glowing credentials and exceptional examples of project work he sent us with his application.'
Meanwhile Vu's family, who spent their life savings funding their eldest son through his masters degree, have appealed for witnesses to the incident to come forward.
Police said a handful of 'key' eyewitness to the incident were caught on CCTV in the moments before the fall, and it is hoped they will be able to help piece together exactly what happened.
Vu had previously graduated with a degree in architecture from Hanoi University and his family had hoped that once he had completed his masters he would return to Vietnam to help pay for his younger brother's education.
