Rodney Mellors

 was a Deputy Administrator to the Chief Administrator Peter Cartwright on the SERVEYOUinc-operated United System Research Base.

He was of negative opinion of Dr Janet Rutherford's research. He was one of the people put into coma by ARC (COMIC: Whodunnit?) and then restored to health thanks to the Eleventh Doctor. (COMIC: The Sound of Our Voices)

Behind the scenes
Although it is not directly stated that he is human, Dr Rutherford's comment made in his presence that toluan salt-beetles are second only to humans in terms of intelligence in the comic story Whodunnit? would be insulting if he were not human.
