Susan completed her graduate training at Carleton University in the experimental forensic psychology program, where she studied jury decision-making. Her current research in the Normative Ethics and Law Lab (NELL) focuses on lay punishment ethics, the insanity defence, and racial/cultural differences in the courtroom. The lab’s aim is to better understand basic social processes and help promote fairness in legal and political decisions.
