Visiting Researchers 

Every year the UCL SpaceTimeLab is happy to host a small number of outstanding visiting researchers and doctoral students. We especially welcome those who closely share our research interests of big-data analytics and network complexity. If you are appointed, you will work closely with members of the SpaceTimeLab to develop a research plan which will be mutually beneficial. In order to make the most effective use of your time with us, we recommend that plans are made well before your visit, typically several months in advance. 

For more information, please see the UCL website: https://www.ucl.ac.uk/multidisciplinary-and-intercultural-inquiry/affiliate-academics or contact Prof Tao Cheng (tao.cheng@ucl.ac.uk)
