Drugs of abuse have the capacity to alter behaviors and shift priorities. Research conducted in the Addiction, Interoception, and Motivation Laboratory broadly revolves around investigating how these effects emerge. This work extends to pharmacological and psychological interventions with the purpose of promoting rehabilitation of compulsive drug-seeking behaviors.

2019-2024 NSERC DG: Manipulating the nature of internal stimuli through conditioning.
The purpose of this research program is to determine the behavioural and neural mechanisms of how an appetitive versus an aversive learning history with a perceptible drug state alters the value of that drug.
2019-2021 NIDA R03: Impact of adding tobacco constituents nornicotine and anatabine on self-administered nicotine.
The purpose of this research program is to determine the altered susceptibility to tobacco following nicotine consumption in adolescents or adults.
2019 CFI JELF: Impact of learning history on individual susceptibility to developing an addiction phenotype.
This grant provides the infrastructure required to measure and manipulate neurochemical correlates of compulsive drug-seeking behaviours.
