Sometimes people hurt others. When they do this on purpose, it's called aggression. I study why people behave aggressively and how we can prevent it. Some of my research has emphasized how poor self-control drives aggression. Self-control failure helps explain why people behave aggressively toward strangers and close relatioship partners. I also use functional magnetic resonance imaging (fMRI) and transcranial direction current stimulation (tDCS) to understand the neural correlates underlying aggression.
