Dr. Margaret Wardle
ART Lab Director
I received my Ph.D. in Clinical Psychology from the University of Illinois at Chicago in 2009 and have focused on understanding and treating addiction throughout my career. The goal of my research is to increase our understanding of drug use and addiction and improve addiction treatment.
I am especially interested in how emotions affect drug use, because when people describe why they use drugs, moods and emotions almost always come up. To investigate how emotions relate to drug use, I do several types of studies. I examine the short-term effects of drugs on emotions by testing how small doses of drugs given in the laboratory change people’s feelings. I also research long-term problems with emotions and mood that occur in addiction, and test treatments to help people cut down or quit. Finally, I work towards harm reduction, which means trying to reduce the negative impacts of drug use without requiring that people stop using drugs.
As an example of my work, recently I have been doing research on how positive emotions affect cocaine use. People with cocaine use disorder often report that they have few positive feelings or sources of joy outside their drug use. My research shows that when people don’t feel able to experience joy and pleasure, they use more cocaine and have more difficulty quitting. I am currently working to test several treatments, including both medications and talk therapy, that I hope will increase experiences of joy and positivity in people with cocaine use disorder, and ultimately help them cut down or quit using cocaine.
