Johanna is a postdoctoral researcher and Canadian Neuroanalytics Scholar at McGill University in Montreal, where she works with Professor Jean-Baptiste Poline on predicting Parkinson’s disease progression using neuroimaging and longitudinal, federated normative modelling. She completed her PhD at the University of Melbourne under Professor Lianne Schmaal and her first postdoc at the Donders Institute under Professor Andre Marquand. A founding researcher in the field of normative modelling, she is now interesed in federated and longitudial normative models, a methodology she developed to characterise individual trajectories of brain change across the lifespan.
Research & Community¶
Johanna’s work sits at the intersection of computational neuroimaging, statistical methodology, and clinical translation, with a particular focus on developing tools that capture individual-level heterogeneity in brain development and disease. She is the lead developer of the velocity centiles methodology and an active contributor to the PCNtoolkit open-source ecosystem. Beyond her research, she is deeply committed to open and reproducible science: she serves as Secretary of the OHBM Open Science Special Interest Group, as a handling editor at the Journal of Open Source Software, and as a contributor to The Turing Way. She is also a Neuromatch Australia Ambassador and a BrainHack Global organiser, reflecting her longstanding investment in building inclusive, community-driven scientific infrastructure.
