Education:

BSc (Psychology, Biology, 2000) - McMaster University, Hamilton, Canada
MA (Psychology, 2001) – Wilfrid Laurier University, Waterloo, Canada
PhD (Psychology, 2006) – Concordia University, Montreal, Canada
Postdoc (Pharmacology, 2009) – McGill University, Montreal, Canada
Postdoc (Psychology, 2012) – McGill University, Montreal, Canada

Research Program:

The current areas of research in the laboratory are as follows;

  • The interplay between addiction and pain in a rat model of patient-controlled analgesia
  • The role of the innate immune system in drug reward and chronic pain conditions
  • The contribution of diet to future hypersensitivity and pain

The laboratory is interested in using animal models to predict clinical efficacy of treatment drugs for addiction and pain. Through the use of genetic, pharmacological and behavioral manipulations, we seek to develop and test new treatments.
