Digital & Computational Psychiatry

Digital Interventions & Intelligence Group (DiiG)

The Digital Interventions & Intelligence Group (DiiG) is a collaborative research initiative that brings together an interdisciplinary team spanning psychiatry, biomedical engineering, biostatistics, machine learning and artificial intelligence, qualitative research, implementation science, and digital ethics. The group co-designs and evaluates digital mental health platforms that leverage individualized modeling to understand, assess, and support mental health and well-being across clinical and real-world settings.

Digital Mental Health Interventions (DMHIs)

Our research deploys a range of digital modalities, including virtual reality (VR), psychoeducational video-based learning, wearable technologies (e.g., smart rings and smartwatches), remote health sensing, and mobile assessments of mood and cognition. These digital mental health interventions (DMHIs) are designed to screen, monitor, and support treatment for conditions such as depression, anxiety, stress-related disorders, and sleep disturbances.

Multimodal digital tools enable the collection of both active data (self-reports, cognitive tasks, behavioral measures) and passive data (physiological and sensor-derived signals) in near real time. When integrated with mobile applications, these platforms support remote monitoring and longitudinal tracking of mental and physical health, facilitating earlier detection of symptom change and relapse risk.

Personalized Modeling, Monitoring, and Prevention

A central goal of DiiG is to develop adaptive, personalized digital systems that learn from individual-level data to inform intervention delivery and clinical decision-making. By combining behavioral, physiological, and contextual signals, our work aims to enhance self-awareness, support healthy behaviors, and provide clinicians with actionable insights to guide care.

All digital platforms are developed with strict attention to privacy, security, and ethical standards, and are fully compliant with patient and participant confidentiality requirements, including HIPAA and corresponding Canadian PHIPA and PIPEDA regulations.
