Marta Maslej
Dr. Marta Maslej is a Staff Scientist with the Krembil Centre for Neuroinformatics (KCNI) at The Centre for Addiction and Mental Health. She completed her PhD in the Department of Psychology, Neuroscience & Behaviour (PNB) at McMaster University, with a focus on understanding the emotional and cognitive symptoms of depression, and implications for treatment. Her current research at KCNI involves using experimental and computational methods to derive insights from clinical data, including text, with the aim of improving assessment, informing treatment decisions, as well as identifying and mitigating bias.
Marta is interested in the ways AI can supplement limitations in human cognition and prognostication to enhance psychiatric care. As part of this work, she co-leads the Predictive Care team with Dr. Laura Sikstrom, which draws on interdisciplinary methods to anticipate impacts of AI applications on patients and providers, with a focus on promoting compassionate and equitable care.
