Mark Changizi

Mark Changizi (born 1969) is an American theoretical cognitive scientist. He is known for his research on evolutionary origins of biological and cognitive design, including the "Perceiving the present" hypothesis to understand optical illusions, the "Nature-Harnessing" theory for the origins of writing, speech and music, the skin-signaling hypothesis for the origins of primate red-green vision, and the rain-tread hypothesis for pruney fingers.

Early life and education Changizi was born in New Jersey in 1969. His mother is American and his father, a physicist, is from Iran. He graduated from the Thomas Jefferson High School for Science and Technology in Alexandria, Virginia. He earned a Bachelor of Science degree in physics and math from the University of Virginia and a PhD in math from the University of Maryland, College Park.

Career In 2002, he won a Sloan-Swartz Fellowship in Theoretical Neurobiology at the California Institute of Technology, and in 2007 he became an assistant professor in the Department of Cognitive Science at Rensselaer Polytechnic Institute. Changizi also conducted research at the University College Cork and Duke University.

In 2010, together with colleague Dr. Tim Barber, Changizi started the research institute 2ai Labs, with the idea to start tech companies based on his research, and subsequently bring funding toward further research at the institute. Changizi took the post of director of human cognition at 2ai.
