Program

IPMI 2021 will feature 3 days of oral and poster presentations of accepted papers. Thorough and lively discussions of the presented scientific results is a hallmark of the IPMI conference series, and we are designing a virtual venue to facilitate and emphasize both scientific and social interactions.
The program will feature live presentations, a keynote by Professor Gitte Moos Knudsen, poster presentations and award ceremony. Between the scheduled events, there will be possibility to meet and discuss both posters and presented orals with the authors. Pre-recorded versions of the talks will be available for viewing outside the scheduled oral sessions.
Discussion groups will meet prior to the conference to read, discuss and prepare questions for all papers. IPMI will in addition have a forum with possibility for offline discussions of all presented papers.

Keynote speaker

  • Gitte Moos Knudsen, Chair, Professor, MD, DMSc Dept. Neurology and Neurobiology Research Unit, Copenhagen University Hospital (Rigshospitalet).
    Gitte Moos Knudsen is a translational neurobiologist and clinical neurologist with interest in advanced methodological developments and applications to address pertinent neurobiological and clinical issues. Her scientific interests include blood-brain barrier transport, neurobiology of cerebral blood flow and metabolism and the neurobiology of cerebral neurotransmission with particular emphasis on molecular brain imaging. Professor Knudsen is leading the Center for Experimental Medicine Neuropharmacology (NeuroPharm) at the Rigshospitalet in Copenhagen. The center has the aim to answer pertinent and basic questions regarding human brain disease mechanisms and predict brain responses to categories of neuromodulatory interventions as well as treatment efficacy. For this purpose, PET brain scanning is used to image brain receptors and receptor occupancy, and fMRI is to evaluate drug effects on the brain hemodynamic response as well as the brains regional interactions, i.e., functional connectivity. Professor Knudsen is in addition director of the Center for Integrated Molecular Brain Imaging (Cimbi), director of the Center for Experimental Medicine Neuropharmacology (NeuroPharm), and PI of the strategic alliance BrainDrugs.
