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.







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.








Honours Students

Caitlin Smith

Morgann Stiles, Honours Student

I am currently volunteering as a research assistant in Dr. Sherry Stewart's addictions lab. I plan to continue my work on gambling addiction through the summer, and into next year, completing my honour's thesis with this research in 2015. I am a recent 2013 Dalhousie graduate with a double major in Psychology and Chemistry, having returned this year to complete my honour's degree. I hope to continue my Psychology career by obtaining a PhD in Clinical Psychology, my main interests being mood and anxiety disorders.

Ben Weilgart-Whitehead, Honours Student

As of sept 2014 I will be in my fourth and final year of my BSc psychology degree.  Supervised by Dr. Sherry Stewart, I am doing my honours project on the relationship between personality traits and gambling outcomes. Using a longitudinal design, I am investigating how motives for gambling interact with personality traits to predict gambling outcomes.  Of additional interest is wether the context in which gambling occurs, such as the presence of friends, or the type of gambling, has an effect on gambling outcomes. 
In the future, I hope to pursue graduate studies in clinical psychology, with a focus on personality disorders.

Annemie Pieterse, P3000 Student

This fall, I will be entering my third year of my BSc in Neuroscience, of which I hope to finish with Honours. During my third year, I will be working on completing an independent research project (PSYO3000X/Y), as supervised by Dr. Sherry Stewart. I am interested in both substance abuse and mental illness, and plan to pursue this area in the future.
