The UK DRN page provides the names of research studies and institutes. You can try to find the principal investigators or institutes/departments involved and contact the focal persons.

Dear Jacqueline, I wonder, where you tried to get the contact data. On the homepage of the Diabetes Research Network (since 2014 under the auspices of NHS-CRN) you will find this information, you are looking for. Kind regards and good luck. Michael

Yeah - I've sent emails but Im not sure if they are to the right person - I will double check and then go and camp out maybe !

When all else fails, knocking on the doors often gets the attention!  ;)

Good luck.
