Dr Philip Zimbardo's long and illustrious career has left an indelible mark on psychology throughout the world.

Perhaps best known for the Stanford Prison Experiment of 1971, he has written more than 50 books and published several hundred articles. He is Emeritus Professor of Psychology at Stanford University and founder of the Heroic Imagination Project, a non-profit organization that recognizes and promotes everyday heroism.

The Stanford Prison Experiment remains one of the most famous social psychology experiments in history. Dr Zimbardo's study saw research participants become 'prisoners' and 'guards' in a mock prison. Dr Zimbardo was also a notable commentator on the Abu Ghraib prison torture in Iraq, drawing parallels between the abuse and the Stanford Prison Experiment.

Some of Dr Zimbardo's most influential research has been on shyness, heroism, the psychology of evil, and cult behavior. He has authored several essential textbooks as well as books for a general readership such as The Lucifer Effect (2007), _The Time Paradox _(2009), and Living and Loving Better with Time Perspective Therapy (2012). He also created the popular television series Discovering Psychology.

Dr Zimbardo has received countless honors and accolades throughout his career, and in 2018 was named one of the 30 most influential counseling psychologists alive by the website Best Counseling Degrees.
