Our Research & Initiatives
Our lab explores the complex interplay between stress, trauma, substance use, and mental health through an integrative neuroscience lens. We combine biological, psychological, and social approaches to understand how early adversity and systemic stigma impact well-being. Grounded in principles of equity, inclusion, and lived experience, our work aims to dismantle barriers to care and inform compassionate, evidence-based interventions. We are committed to meaningful knowledge mobilization and the training of interdisciplinary scholars equipped to transform mental health and substance use health systems
Stigma
Only one in ten individuals with a substance use disorder will access formal services and support. This gap is largely driven by stigmatizing attitudes, beliefs, and structural barriers. Our research program aims to understand how stigma operates across the substance use health spectrum, and how it influences access to care, health outcomes, and experiences.
Problematic Social Media Use
As social media becomes more integrated into our lives, understanding its impact on well-being is increasingly important. Our lab explores the neurological and behavioural factors behind problematic social media use, drawing parallels to substance use disorders. This research supports the development of clearer diagnostic criteria for behavioural addictions and informs strategies to prevent potential negative mental health effects linked to excessive social media use.

Cannabis
Our research investigates how cannabis use intersects with early-life trauma, stress regulation, and mental health outcomes through a biopsychosocial lens. While cannabis is widely used across Canada, we know relatively little about the biological and psychological factors that shape its impact on stress, coping, and vulnerability to conditions such as anxiety, depression, and suicidality, especially among those with histories of adversity and among emerging adults.
Pedagogy
The work of Dr. Hellemans in the Scholarship of Teaching and Learning (SoTL) is grounded in a deep commitment to improving student success, particularly during key academic transitions such as the first year of university. As Associate Dean (Student Recruitment, Wellness, and Success), she focuses on identifying barriers to student achievement and developing evidence-based interventions that enhance academic outcomes, wellness, and equity
