Gillian Alcolado

Pam Collins, Gambling Lab Manager

I completed my undergraduate studies in May 1999 at Dalhousie University, receiving a first class honours degree in Psychology. Since graduation, I have been managing the Dalhousie Gambling Lab. I have had the privilege to be both a student and employee of Dr. Stewart's, and I love the variety and learning opportunities that my job affords me.


Jennifer Swansburg , Project Manager, Gambling Study

I recently returned to school completing a BSc in Psychology at Dalhousie University. Over the past few years I have enjoyed working as a volunteer on several research studies in Dr. Stewart’s lab. Currently, I am working as a project manager on a Motivation-Matched Treatment Study with Pathological Gamblers.





Research Associates

Roisin O'Connor

Nancy Comeau, Ph.D. (Interdisciplinary: Psychology, Community Health & Epidemiology, Philosophy)


My background involves an interdisciplinary approach to mental health and addictions within an ethical framework. My interests include development of culturally relevant youth interventions focusing on preventing alcohol and other substance abuse problems or intervening early before risky substance use behavior becomes chronic and ingrained.

Graduate Students


Annie Chinneck , Ph.D. Student

My research is forensic-centered. I am particularly interested in studying the comorbidity of both behavioural and chemical addictions and mental health in criminal and police populations. I recently graduated with a Bachelor from Carleton University and am just now starting my PhD in Clinical Psychology at Dalhousie.   


Melissa Stewart, Ph.D. Student

My research interests reside primarily in the etiology, treatment, and prevention of problem gambling. Specifically, I am interested in psychological factors that play a role in the development and maintenance of problem gambling, as well as responsible gambling strategies aimed at reducing the potential harm associated with problem gambling. I recently completed my MA thesis, which examined whether a pop-up message reminding VLT gamblers when they have reached monetary limits set prior to gambling is effective in encouraging gamblers to play within their limits.



Jamie-Lee Collins, Ph.D. Student

My research interests lie in the domain of personality traits, motivations for alcohol consumption, and alcohol problems. More specifically, I am interested in researching how certain personality traits such as neuroticism and extraversion can influence whether an individual is internally or externally motivated to consume alcohol and how this can create the potential for corresponding alcohol problems.


Susan Battista

Marie-Eve Couture, Ph.D. Student

I am interested in polysubstance use and co-morbid psychological disorders, and my dissertation will hopefully focus on that subject. Currently, I am investigating pathological gamblers, co-morbid psychological disorders, and possible treatment options adapted to each gambler subtype. I recently completed an honours thesis that investigated smokers, their processing of threatening health messages, and whether this processing could be increased using classical conditioning.


Heather Fulton , Ph.D. Student

I am co-supervised by Drs. Sherry Stewart and Sean Barrett.  My dissertation examines prescription opioid use, other substance use and mental health symptoms among individuals enrolled in a low threshold methadone program.  My research interests are primarily: prescription medication misuse, addictive disorders and co-morbid mental illnesses and/or pain.


Valerie Grant

Janine Olthuis, Ph.D. Student

My research interests lie in the area of alcohol use among adolescents and young adults and its relationship with anxiety and athletic participation. I am interested in athletic participation as both a risk factor for hazardous alcohol use in addition to as a component of treatment for anxiety sensitivity and related disorders. I recently completed my honors thesis looking at the relationship between college student-athletes' perceptions of the extent to which their parents, teammates, and coaches approve of the use of alcohol, and their own levels of hazardous alcohol use.


Brigitte Sabourin

Susan Battista, Ph.D. Student

I am investigating the relationship between social anxiety and alcohol use. Specifically, I am interested in how alcohol affects levels of rumination in socially anxious individuals after they attend social events or engage in social interactions.



Brigitte Sabourin, Ph.D. Student

For my dissertation I am investigating the role of physical exercise/ running as an interoceptive exposure component of a brief cognitive behavioural treatment for decreasing anxiety sensitivity in University women.




Honours Students

Caitlin Smith

Laura Lambe , Honours Student

I am currently in my fourth and final year of my honours undergraduate degree (BSc in Psychology). Co-supervised by Dr. Sean Mackinnon and Dr. Sherry Stewart, my honours thesis will explore the reciprocal association between alcohol problems and relationship conflict in young adult romantic dyads over a longitudinal time period. Previously, I have also completed an independent research project and worked as a research assistant in the lab. In the future, I plan on pursuing graduate studies in clinical psychology, with a focus on substance use.
