RADiANT Inaugural Event

  • The first RADiANT event, hosted by Hertfordshire Partnership University NHS Trust, held in Hatfield on 13th June 2019 was a great success.  
  • RADiANT was introduced by Professor Asif Zia and Professor Sabyasachi Bhaumik, and our convenor Dr Regi Alexander. Following that, we had presentations from a number of fantastic speakers on a range of topics.  
  • Over 100 delegates attended, from a range of multidisciplinary backgrounds. Most importantly, a number of our advisory board Experts by Experience joined us, and their presentation, contributions to the panel discussions and question and answers were invaluable.
