He is best known for pioneering the FBI's offender profiling in the 1970s and 1980s with fellow FBI instructor Howard Teten. Mullany received a master's degree in psychology and counseling from Manhattan College. He began working for the FBI in the mid-1960s. His primary position in the FBI was in the Behavioral Analysis Unit, where he embarked on his work in offender profiling.
