The UK National Interventional Radiology Trainee Research (UNITE) Network is a junior/trainee led research network. We are supported by the BSIR, BSIRT & IR Juniors. Our aims are to promote academic interventional radiology, run multi-centre projects and provide mentorship.

Steering Committee: Robin Borchert, Jim Zhong, Indrajeet Mandal, Gregory Makris
