Jan Malm is professor of Neurology, head of division and together with prof Anders Eklund leader of the hydrocephalus research group. He has about 30 years of clinical experience in the investigation and treatment of hydrocephalus. His research interest has been focused on various aspects of hydrocephalus, CSF dynamics, blood flow measurements and in recent years, the spaceflight-induced ocular syndrome (SANS) in astronauts.
 
Malm was principal investigator for the epidemiological study INPH-CRasH, and is currently working with VESPR, a prospective study performing MRI in 1000 elderly with gait disturbances. He is also a principal investigator in the American PENS 2 study, randomizing INPH patients to open or closed shunt. Malm has national research grants from the Swedish Heart- and Lung Foundation, the Swedish Brain foundation and the Swedish space agency. In 2020, Malm received the “Robert H. Pudenz Award” for excellence in Hydrocephalus and CSF physiology. He was also awarded the “Marmarou lecture” at the international hydrocephalus meeting in Vancouver in 2019.
