Present position

I am working on my doctoral thesis at the University of Oulu. I have a degree in biomedical engineering, and I focus on multidimensional signal analysis in neuroimaging research.

Research summary

Currently I am solving technical challenges on assessment of brain clearance by measuring cardiovascular pulse propagation in human brain. My latest findings show that pulsations are altered in Alzheimer's disease, matching latest discoveries about the glymphatic system in animal research.
