He received his Ph.D. from the University of Massachusetts at Amherst in 2009. His mentor was Icek Ajzen. Much of Mark's work is guided by Dr. Ajzen's theory of planned behavior. Mark's research interests generally focus on the role of information in behavioral decision-making and eventual behavior.
