How do you tell people who you are (what associations are you affiliated with)?

For example, “Chagnon says that people lied to him about who their relatives were.” The tone of your paper should be professional, not tongue-in-cheek. Who are you (describe both ascribed and achieved characteristics)? How do you tell people who you are (what associations are you affiliated with)? How are you similar to, how are you different from, everyone else?
