Marcel Danesi (born 1946) is a current Professor of Semiotics and Linguistic Anthropology at the University of Toronto. He is known for his work in language, communications, and semiotics; being Director of the Program in semiotics and communication theory. He has also held positions at Rutgers University (1972), University of Rome "La Sapienza" (1988), the Catholic University of Milan (1990), and the University of Lugano.
He is the Editor-in-Chief of Semiotica: Journal of the International Association for Semiotic Studies and is a past-president of the Semiotic Society of America.
Marcel Danesi is the author of over 100 books. His works consider the semiotic and anthropological aspects of emoji, popular culture, puzzles, crime, youth, and a range of other topics.
His book Semiotics of Emoji published in 2016 for the Bloomsbury Advances in Semiotics Series, helps further our understanding of the visual language of emoji (Japanese for picture-word). Rather than dismissing emoji as a tool for the uninformed, Danesi traces back to the anthropological and sociological roots of human cognition by discussing the creative and logical sides of the brain at work in the use and creation of this new visual language. 
He is a pioneering figure in the introduction of the disciplinary subspecialty of forensic semiotics. In 2013 he published Signs of Crime: Introducing Forensic Semiotics.
His works typically offer readers an approachable invitation to the use of semiotics to help explain everyday phenomena. For instance, his book Quest for Meaning: A Guide to Semiotic Theory and Practice provides readers with a simple three-fold way of considering semiotic inquiry as trying to answer "What does it Mean? How does it convey meaning? And Why does it mean what it means?"
