Recently, Jonathan Mattingly has been a detective of sorts, delving into partisan gerrymandering in North Carolina. (Gerrymandering is when one party manipulates voting districts for their own gain.) Mattingly is chair of the math department at Duke and his mathematical analysis of the state’s 13 Congressional districts was used in a court ruling that declared the state's maps unconstitutional. He says what he uncovered in his research could be used to address gerrymandering in other states.
