I received my Bachelor of Science degree in chemistry and biology from Dalhousie University. Over the course of my program, I focused mainly on drug and molecular design. During my undergraduate degree I worked on a research project studying the impact of Memantine on Alzheimer’s disease. Another project I worked on was the study of transgenic Caenorhabditis elegans as a model system in therapeutic science and medicinal biology. After graduating I started working as a research assistant at Dr. Stewart’s laboratory. I have always been interested in how drugs impact an individual’s behavior, and working in Dr. Stewart’s laboratory allows me to further pursue this interest
Parnell MacDavis-NevinMAAC Lab Project Manager
I graduated from St. Francis Xavier University in 2010 with B.Sc. Psychology with first class honors. After graduation I obtained my M.Sc. Neuroscience at Carleton University. I began my work in Dr. Stewart’s lab as a research coordinator for the Caring Campus Project; a multi-site Movember funded initiative to reduce harmful alcohol use in undergraduate students. Presently I am a research coordinator for a collaborative study with Dr. Janine Olthuis (UNB) and Dr. Margo Watt (StFX) that is a randomized control trial of cognitive behavioural therapy (CBT) for anxiety sensitivity vs. disorder-specific CBT.
Noelle StricklandPh.D. Student
I completed my Master's degree at Carleton University and I am in the first year of my PhD in Clinical Psychology. I am interested in how social anxiety and drinking motives influence alcohol use in adolescents and young adults. In future studies I aim to explore how context (e.g., alone, with friends) may change drinking behaviours for socially anxious young adults.

Marie-Eve CouturePh.D. Student
I am currently completing my PhD in clinical psychology under the supervision of Dr. Sherry Stewart. I recently completed my clinical psychology residency at the Nova Scotia Health Authority. I am currently writing up my doctoral dissertation and will be defending this year. My dissertation focuses on increasing understanding of the high comorbidity between depression and alcohol use disorders. I use both qualitative and quantitative methods in my research. Specifically, I have employed qualitative interviews with students who self-report drinking to cope with depression to learn more about the reinforcing effects of alcohol in this group of drinkers. I have also conducted lab-based research to examine the impact of alcohol on depression-relevant cognitive biases in students who report drinking to cope with depression. I am an active researcher in the international DRINC collaboration, examining drinking motives in undergraduates cross-culturally.

Kayla JoyceHonours Student
This upcoming fall, I will be entering into the final year of my BSc, Honours in Psychology. In 2015, I had completed an independent research project in Dr. Stewart’s lab which examined woman’s mood, drinking motives and alcohol consumption across the menstrual cycle. Completing this independent research project has increased my interest in how a woman’s menstrual cycle phase effects one's motivations and mood. Supervised by Dr. Sherry Stewart, my honours project will use a daily diary method to examine links present between mood, gambling motives and gambling behaviour across the menstrual cycle. After graduation, I would like to pursue my Master’s degree in Clinical Psychology
Zarrin GhafariHonours Student
This fall, I will be entering the fourth year of my BSc, Honours in Psychology. I started volunteering in Dr. Sherry Stewart's lab this past January. Due to my interest in addictive behaviors and gambling, I decided to pursue my honours in this particular lab. In relation to my honours project, supervised by Dr. Sherry Stewart, I will examine whether an electronic gambling machine can cross-prime motivation for stimulants in groups of participants who regularly use cocaine or crack cocaine, but have no gambling-related disorder. After completing my undergraduate studies, I am looking forward to enrolling into the graduate program of Clinical Psychology.
Trevor ShannonP3000 Student
A 3rd year undergraduate Psychology student, I developed an interest in the psychology of addictive behaviours just over two years ago when I myself decided to stop drinking. This interest ultimately spurred my return to university to pursue a degree in Psychology, with the hope of eventually parlaying it into further post-graduate studies and a career in the field. I have been involved with the Stewart lab for just less than a year, and have been fortunate to work on the Caring Campus Project and now on my own P3000 project examining the drinking motives of same-sex friends, aged 18-25, who have known one another for less than a year. I am looking forward to delving further into the project, and getting to partake in other projects in the Stewart lab in the future.
Michelle TougasComprehensive Student
I completed my Master’s in Community Health and Epidemiology at Dalhousie University and am currently a PhD student in the Clinical Psychology program. My work with Dr. Stewart is exploring the influence of drinking motives (e.g., to cope with anxiety or depression) on alcohol consumption in friendship dyads experiencing conflict.
Elizabeth McKayComprehensive Student
I am in my first year of the Clinical Psychology program. I completed my BSc (Hons) in Psychology at Dalhousie, focusing my research on children’s language development; particularly, factors that aid successful reading comprehension. Further, I studied the academic abilities of university students with undiagnosed reading difficulties. Now, for my second comprehensive project for which I will be working with Dr. Stewart, I am continuing to study the academic abilities of university students with undiagnosed reading difficulties, but incorporating information about personality traits and substance use to determine how these factors influence the academic success of this population. I am greatly looking forward to broadening our understanding of this population’s academic abilities and the factors that influence said abilities, as well as for the opportunity to work with Dr. Stewart!
Leah JonesMedical Student
I graduated from Dalhousie in 2013 with a BSc in Biology, and am currently in Dalhousie Medicine's Class of 2018. My research interests lie in motives for use and addictions among marginalized populations. Clinically I am most interested in being a generalist, potentially a career in Emergency Medicine where hopefully I can practice within my research interests!
