Lise Dassieu, PhD
Research and Policy Analyst


Lise’s areas of expertise include opioids, substance use and chronic pain, stigma and the social dimensions of substance use.


Throughout her career, Lise Dassieu has been interested in learning about the perspectives and experiences of people who use drugs. She enjoys collaborating with people with lived experience of substance use and learning from them. She joined CCSA in February 2022 to gain opportunities to develop research projects in line with the realities of people who use drugs, policy makers and other stakeholders.  

From 2017 to 2021, Lise led several qualitative research projects examining the experiences of people living with concurrent chronic pain and substance use during the opioid overdose crisis. She published articles based on these projects in peer-reviewed journals such as Social Science and Medicine and The International Journal of Drug Policy. These projects had a significant scientific and policy impact.

Lise served as a postdoctoral researcher in the Addiction Research Chair of the University of Sherbrooke and as a senior postdoctoral researcher at the University of Montreal Hospital Research Centre. She earned her PhD in sociology from the University of Toulouse in France.

In her spare time, Lise tries her hand at knitting, mountain biking and hiking.
