Dr Jessica Hartmann joined the team in April 2025 as a Senior Research Fellow. She specialises in predicting and mitigating emerging mental ill-health, focusing on at-risk mental states, transdiagnostic approaches, and clinical staging. Dr Hartmann's research uses intensive longitudinal data and dynamic modelling to improve early detection and intervention strategies in psychiatry, with a particular emphasis on the role of sleep in the onset of mental illness.

She holds a PhD from Maastricht University, where she focused on sleep, affect regulation, and digital interventions using Ecological Momentary Assessment (EMA). She was awarded the NWO Rubicon Fellowship and subsequently the UoM McKenzie Fellowship, which supported her postdoctoral research at the University of Melbourne and Orygen. During this time, she developed the CHARMS High-Risk Paradigm as part of the clinical staging framework and conducted research integrating dynamic systems theory to predict critical transitions in mental health. She also held a Research Fellow position (now Visiting Researcher) at the Department of Public Mental Health, Central Institute of Mental Health in Mannheim.

Dr Hartmann contributed to major projects funded by NIH, NHMRC, Wellcome Trust, and Horizon Europe, ßsecuring over AUD $40 million in competitive research funding. She is Co-Lead of the Digital Biomarkers and EMA Stream of Accelerating Medicines Partnership for Schizophrenia (AMP SCZ). Dr Hartmann has over 80 peer-reviewed publications, with more than 3,600 citations.
