For the period 1999 to 2009 it was the 13th most-cited university in the world (and the most-cited in Europe). There has been at least one Nobel Prize winner from UCL every decade since the establishment of the Nobel Prizes in 1901. There are 29 Nobel Prize winners and three Fields Medalists amongst UCL’s alumni and current and former staff, the most recent being Sir Charles Kao, who received the Nobel Prize for Physics in 2009.
