Research Interests

  • Alcohol and Drug Abuse and Prevention
  • Mechanisms of Behavior Change
  • Risk and Protective Factors Associated with Cannabis Use

My various research interests focus on improving prevention and early intervention techniques for promoting and motivating health behavior change. Specifically, I am interested in process research with the goal of better understanding and identifying effective elements of therapeutic interventions, particularly Motivational Interviewing, in order to reduce the impact of substance abuse and problems. Additionally, I am interested in understanding the risks and/or benefits of cannabis use across various populations.

Dr. Ladd plans to recruit a graduate student for Fall 2021 admission to the Experimental Psychology PhD Program.
