Andrea Howard (Director)
My research primarily examines mental health (depression, anxiety) and substance use (alcohol, cannabis, tobacco, and other drugs) in adolescence and the transition to adulthood. Current studies with collaborators include: (1) evaluating the developmental course of substance use from late childhood to the mid-twenties, comparing people with and without childhood histories of ADHD; (2) the intersection of self-control, mental health, and alcohol use in undergraduate students; (3) contexts that impact well-being in adolescence and the transition to university, particularly parent involvement and smartphones/social media.
I am also actively engaged in research and pedagogical work on quantitative methods for developmental and clinical research. Recent projects examined data visualization strategies and participant compliance with ecological momentary assessment protocols.

Robert Coplan
My research focuses on experiences of solitude across the lifespan and across cultures. In particular, I am interested in the development and implications of shyness, social withdrawal, and preference for solitude. My most recent research projects have focused on: (1) the costs and benefits of solitude in childhood, adolescence, and adulthood; (2) the challenges faced by shy and anxious children at school; and (3) the meaning and implications of social withdrawal in different cultures.

PhD Student, Psychology (Vanier Scholar)
Previous Degrees:
- Master of Science, Applied Science, Saint Mary’s University
- Bachelor of Arts, Psychology, Saint Mary’s University
Research Interests:
I am a fifth-year PhD student in Developmental Psychology, working under the supervision of Dr. Robert Coplan. My research currently focuses on experiences of solitude during adolescence and emerging adulthood. I am specifically interested in looking beyond time alone to consider how the “what” (i.e., solitary activities), “why” (i.e., internal motivations), and “where” (i.e., environmental context) of solitude interact to predict well-being. I am also enthusiastic about advanced statistical techniques and hope to graduate with a concentration in Quantitative Methodology.
As a secondary line of research, I use participatory action, mixed (qualitative/quantitative) research methods to examine how community-based interventions can be leveraged to enhance ecological resilience in violence-affected youth.

Previous Degrees:
- Master of Arts Psychology, Carleton University: Data Science Specialization
- Bachelor of Arts Honours Psychology, Carleton University: concentration in Social and Personality Psychology and minor in Neuroscience and Mental Health
Research Interests:
I am a first-year PhD student working with Dr. Robert Coplan. My research interests include examining the social and personality aspects that influence one’s experience of solitude. I am involved in a variety of projects with varying methodologies. Presently, I am researching the paradox of having a social identity as someone who enjoys solitude, and the various impacts of this social identity has on experience of solitude. I am also interested in examining the use of chatbots and AI to meet socialization needs. Finally, I am interested in methodology and statistics and I’m pursuing a concentration in quantitative methodology.

Anne Bowker
As a developmental psychologist, I have always been interested in transitions – how early adolescents cope with the daily hassles associated with puberty, peer pressure and parental conflict; the role that extra-curricular activities play in positive youth development throughout high school; the transition from adolescence to young adulthood and developmental phase called emerging adulthood; the transition to university and most recently, the transition to mid-life, understanding how women navigate the menopausal transition and it’s impact on successful aging.
My current research focus is two-fold: a) A focus on emerging adulthood and the transition to university; identifying key factors that predict student engagement, with a particular interest in how supportive relationships with parents, peers and faculty, can facilitate this transition; and b) A focus on mid-life, understanding the psychological impact of menopause, the role of significant relationships in this transition and how body image at mid-life, influences well-being.

Katie Gunnell
I am interested in understanding the psychological correlates and mechanisms of psychological health and behaviour across various populations including youth, adults, and individuals diagnosed with osteoporosis. I examine all aspects of the psychological health continuum including ill-being (e.g., symptoms of depression), hedonic well-being (e.g., positive affect), and eudaimonic well-being (e.g., vitality). The behaviours I am interested in understanding include physical activity and recreational screen time (e.g., watching TV, playing video games). In an effort to better understand how to enhance psychological health and physical activity and decrease screen time, I am particularly interested in psychological needs (e.g., competence, autonomy, and relatedness) and motivation as mechanisms for change. In a secondary line of research, I am interested in psychometrics and quantitative statistics.

Vivian Lee
My research focuses on the emotional and mental health of children and youth with autism and other neurodevelopmental disabilities. My work includes the investigations of child-, parent-, and system-level characteristics, and the relationship between these factors, that either support healthy emotional development or exacerbates difficulties in the child and for the family. I am also interested in the impact of these factors on overall parent and family wellbeing. Additionally, I have an interest in implementation science and program evaluations, and working alongside community-based autism providers and advocacy groups, I am investigating the impact of the COVID-19 pandemic, as well as participation in psychosocial interventions on the mental health and wellbeing of autistic youth and their caregivers.
