Pablo RomeroVisiting Post Doctoral Fellowship from the University of Malaga
I completed both my BSc. in Psychology and Master in Clinical and Health Psychology at the University of Malaga (Spain). After that, I got my Doctorate in Clinical Psychology Hospital of Jaen (Spain), and my Ph.D. also at the University of Malaga (with distinction and European mention). Finally, I got a Master in Neurosciences at the University of Cadiz (Spain).
I have more than 10 years of clinical experience with patients with addictions, mood, anxiety and psychotic disorders in both Spanish Public Health Services and my own private practice in both group and individual formats. My research interests go from cognitive-behavioural processes involved in psychological disorders from both transdiagnostic and disorder-specific approaches, to the interplay of biological and psychological variables in the development, maintenance and treatment of mental disorders, but also the implementation of Internet-based psychological therapies.

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

Tristan ParkHonours Student
I am going into my 5th year at Dalhousie University to complete my BSc, Combined Honours in Psychology and Biology. In May 2017, I was given the opportunity to work in Dr. Sherry Stewart’s lab as a summer RA. My interest in depression and anxiety related mental health disorders led me to pursue an honours project under the supervision of Dr. Stewart. Starting in the fall, my honours project will explore the use of marijuana in veterans who have PTSD and how exposure to marijuana and trauma cues impacts mood and craving. After graduation, I hope to enroll in a Master’s program to study Clinical Psychology
Trevor ShannonHonours Student
A 4th year undergraduate honours student, I developed an interest in the psychology of addictive behaviours nearly three 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 over a year and a half now, and have been fortunate to work on the Caring Campus Project, as well as my own P3000 project examining the drinking motives of same-sex university aged drinking dyads. I gained valuable insight and research experience through the project, and am looking forward to commencing my honours thesis at the start of the upcoming school year.
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!
