Student or Learner
Would you be kind enough to tell me whether I am right with my interpretation of the expressions in bold in the following sentence?
Our speakers today head up the Blue Bay Police Sex Crimes Unit – Detectives Ray Duquette and G;oria Peerz.
our speakers = our lecturers
head up = be head of ; be the first or leading member of (a group) and excel
Thanks for your efforts.
