He's a man with brown/gray hair, glasses, a white coat, a light blue shirt, a dark blue tie, brown pants, and black shoes.

It's not the Male Pharm Team Researcher.

Answer 1

Most likely just some random background character inserted into the scene. Not every character in the crowd scenes are established characters.
