I am a behavioural pharmacologist who studies the behavioural and neural effects of drugs, with a special emphasis on drugs of abuse.

My research is focused on the brain’s endocannabinoid system. Using behavioural and immunohistochemical techniques, I examine how cannabinoid receptors are involved in normal behaviour (e.g., learning, memory, feeding, locomotion), pathological behaviour (e.g., addiction), and how cannabinoids interact with non-cannabinoid drugs to alter behaviour and brain activity.

Note that Dr. Mallet is unable to respond to elementary or high school students asking for help or an "expert opinion" related to their school assignments or projects.

I typically supervise student projects in the following areas (but other topics would be considered):

• Long-term consequences of cannabinoid system dysfunction caused by early life adversity.
• Role of the endocannabinoid system in learning and memory.
• Behavioural pharmacology of neutral CB1 receptor antagonists.
• Behavioural interactions between cannabinoid and non-cannabinoid drugs (e.g., ‘ecstasy’, nicotine, alcohol, heroin, cocaine).
• Involvement of endocannabinoids in drug reward and addiction.

Note that I am presently on sabbatical until July 2032.

I have already accepted several undergraduate and graduate students for the 2023-2024 academic year. I do not NOT have the capacity to accept any additional honours thesis or graduate students for the 2023-2023 academic year.
