Geir Andre Ringstad

Geir Andre Ringstad is an Associate Professor at the Department of Radiology and Nuclear Medicine, University of Oslo, specializing in neuroimaging and cerebrospinal fluid (CSF) dynamics. His research focuses on the glymphatic system, CSF tracer studies, and MRI-based quantification of brain clearance mechanisms.

Research Themes

• Neurofluid dynamics and glymphatic dysfunction in normal pressure hydrocephalus, Chiari malformation, and pineal cysts
• Impact of sleep deprivation on CSF tracer clearance
• Novel MRI protocols for assessing CSF disorders and neuroimmune interfaces

Publications cover diverse topics including glymphatic-lymphatic coupling, CSF flow modeling, contrast agent safety, and computational analysis of neurofluid pathways. Collaborative work spans neurosurgery, endocrinology, and biophysics.
